Citrus waste fibres for natural cosmetic and bioplastic packaging

In this work new biocomposite materials from wasted citrus peels has been validated for a value-added packaging and novel cosmetic products. Specifically, extracted natural fibres and dehydrated pulp from citrus fruit were combined with polylactic acid and other additives as materials for the production of bio-based packaging jars and cosmetic products. For the composition of the packaging an orange powder (dehydrated wastes) was found to be the best performing, while orange comminute, which results from milling the orange peel, was most suitable for composition of the cosmetic formulations. Polylactic acid was compounded with citrus fibres by up to 25 wt.% by twin screw extrusion and processed via injection moulding, one of the most widespread processing technologies for producing rigid packaging containers. Composites were characterized, defining their mechanical, morphological and thermal properties. Validation of packaging thermostability performance was performed by Heat deflection temperature in compliance to ISO75 and VICAT softening temperature in accordance with ISO306. Compatibility tests of packaging demonstrators with newly formulated cosmetic products has been investigated as well. An accelerated compatibility test of the cosmetic jars with water and oil-based simulants was performed at ambient temperature, -5 °C, and at 45 °C. The results indicated that new cosmetic packaging are not consistent with water-based cosmetic formulations but are compatible with products based on natural oils. While the price of these products is generally higher than those using conventional plastics, they are competitive for premium cosmetic brands.

Significance of transcrystalline layer formation on electrical conductivity of polyamide 6-carbon nanotube nanocomposites: An experimental and theoretical study

Electrical conductivity and mechanical properties of PA6/carbon nanofillers nanocomposites are highly dependent on the formation of PA6 transcrystalline layers onto the carbon nanofillers. In the current study, the substantial effects of PA6 viscosity and CNTs modification on transcrystalline layer formation in nanocomposites were investigated both experimentally and theoretically. FESEM, TEM, and solvent extraction observations showed almost identical morphological features for all samples, with well-dispersed carbon nanofillers within the matrix, and dispersed droplets morphology. Therefore, the differences in electrical conductivity among various nanocomposites were attributed to the only variable, which was differences in PA6 transcrystalline layer formation. It was found that employing high viscosity PA6, as well as modifying CNTs, both result in reduced transcrystalline layer formation and thus higher electrical conductivity, as corroborated by the theoretical modeling. Moreover, the evaluation of mechanical properties further elucidated that the transcrystalline layer formation can improve the tensile strength, Young’s modulus, and heat deflection temperature. Hence, on the one hand, transcrystalline layer formation endowed nanocomposites with superior mechanical properties due to the strong interfacial adhesion between the nanofillers and polymer matrix. On the other hand, however, it decreased the electrical conductivity by hindering electron tunneling through the dense and insulative transcrystalline layers.

Improving the high-temperature performance by constructing restricted amorphous regions in PEEK

Improving the high-temperature performance of polymers through crosslinking without compromising properties such as ductility and processability remains a significant challenge. In this study, we synthesize a cross-linkable poly (ether ether ketone) end-capped with phenylethynyl groups (PEEK-PEPs) and subsequently melt-blended it with semi-crystalline PEEK to create the PEEK alloy (PEEK/PEEK-PEPs). Under thermal treatment, the curing process of PEEK-PEPs is dominated by the formation of a cross-linked network, accompanied by chain growth reactions. The chain growth reaction will gradually become the dominant reaction as the treatment time increases. These results are validated by successive self-nucleation and annealing, as well as measurements of gel fraction and viscosity before and after thermal treatment. With this approach, the storage modulus (E') of PEEK/PEEK-PEPs is improved by 95 % at 290 °C, and the heat deflection temperature (HDT) is increased by 25 °C. Meanwhile, the tensile strength of PEEK/PEEK-PEPs at room temperature and 150 °C increases to 125 MPa and 72 MPa, respectively, which is 30 % and 31 % higher than that of pristine PEEK resins, while the strain at break remains at the same level as PEEK. These findings potentially provide an advanced polymer alloy preparation method for high-temperature applications, particularly in extreme environments.

PP/MACAIBA almond composites: Effect of SEBS-MA and EPDMA-MA compatibilizers on the mechanical properties and biodegradation

There is a need to develop environmentally friendly materials, especially plastics, that minimize environmental pollution. In this sense, polypropylene (PP) composites were produced with 20 wt% of Macaiba almond powder (MA*) and compatibilized with SEBS-MA and EPDM-MA to carry out a biodegradation investigation of these composites. Mechanical properties (impact, tensile), heat deflection temperature (HDT), scanning electron microscopy (SEM), and Fourier transform spectroscopy (FTIR) experiments were performed. These analyses verified that the best plasticization was reached in the composites with 15% of SEBS-MA and EPDM-MA, indicating an interaction between phases. The impact strength and elongation at break of the PP/MA*/EPDM-MA and PP/MA*/SEBS-MA composites increased significantly, suggesting tough behavior. Biodegradation occurred in the soil for 120 days, and both PP/MA*/10EPDM-MA and PP/MA*/15EPDM-MA demonstrated a mass loss of about 4.68% and 4.0%, respectively. Although PP is not biodegradable, the results show that macaíba almond powder can biodegrade in the PP matrix.

Fiber treatment impact on toughness and interfacial bonding in epoxidized soya bean oil compatibilized PLA/PBAT bamboo fiber composites

Biodegradable plastics such as Poly(lactic acid) (PLA) and polybutylene adipate terephthalate (PBAT) are commonly used in composite fabrication and applications. However, their inherent properties limit their use. In this study, Epoxidised soyabean oil (ESO) compatibilized PLA/PBAT was filled with modified bamboo fiber (BF). The BF was modified in a two-stage environmentally friendly process involving steam treatment followed by a new approach to hydrophobic natural fiber modification with naturally occurring fatty acid (myristic acid) (MA). Then, the ESO/PLA/PBAT/BF composite was fabricated, and the influence of the new fiber modification method on the toughness and interface bonding of the composite was studied. The composite was characterized using mechanical analysis, scanning electron microscopy (SEM), thermogravimetry analysis (TGA), Fourier-transform infrared spectroscopy (FTIR), X-ray diffraction analysis (XRD), water contact angle measurement, and statistical methods. The melting behavior was also studied using Vicat softening and heat deflection temperatures. The ESO compatibilisation improved the compatibility of the PLA/PBAT blend, resulting in a continuous PLA/PBAT phase, as evidenced by the interface modulus, glass transition temperature, and fractured surface. The modification of BF enhanced its dispersion in the matrix and improved interfacial adhesion. Elongation at break and impact toughness were improved by more than double compared to neat PLA. Adding PBAT and modified BF to PLA resulted in a thermally stable composite. The statistical analysis results suggested that BF modification and BF loading significantly influenced the composite strength and toughness (P ≤ 0.05). The tough and flexible composite material can used in flexible/lightweight and impact-resistant applications, consumer goods, and heat shields.

Multi‐featured epoxy composites filled with surface‐modified PTFE powders treated by Na‐naphthalenide system

AbstractThis study aimed to produce new multi‐featured epoxy composites that are advanced in terms of mechanical properties, wear and impact resistance, and glass transition and heat deflection temperatures. Epoxy composites filled with chemically surface‐treated poly (tetrafluoroethylene) (PTFE) powders at various ratios were prepared to obtain these improved properties. The chemical treatment was carried out via a Na‐naphthalenide system. After this treatment, the x‐ray photoelectron spectroscopy results presented the existence of functional groups such as OH, carbonyl groups, and CC unsaturation points on the surface of the PTFE powders. On the PTFE surfaces, while the atomic ratios of carbon and oxygen were substantially increased, the fluorine ratio presented a significant decrease after the chemical treatment. However, the wear rates of the novel composites were highly advanced despite this large decrease in the fluorine ratio on the surface of the PTFE powders. Moreover, functional groups such as OH, carbonyl groups, and CC unsaturation points and spongelike or network structures on the PTFE surfaces provided the opportunity to obtain strong adhesion and interfacial bonding between the surface‐modified PTFE powders and the matrix. Strength and modulus values showed substantial enhancement besides the IZOD impact resistance. All glass transition and heat deflection temperatures were also substantially improved.

Towards FBG-Based Shape Sensing and Sensor Drift for a Steerable Needle

Continuum manipulators contribute to promising improvements of minimally invasive surgical procedures due to their compliance, small size, and ability to navigate anatomical pathways. Feedback of the shape of such robots within the body is currently being researched through the use of fiber Bragg grating (FBG) sensors. As the size of the robot is reduced, placement of the sensors becomes increasingly challenging, often relying on glues and epoxies. In this article, a triplet of FBG fibers is used for shape sensing of a tendon driven continuum joint. Tests are performed to show the accuracy of reconstruction using this sensor both alone and incorporated in a tendon-driven continuum joint. A repeatable sensor drift was observed during prolonged deflection which caused an increase in error of up to 0.218 mm over a 10-min period. Results showed the effect of the repeated and sustained deflection on shape reconstruction under various deflection conditions and temperatures.

Numerical study of continuous Czochralski (CCz) silicon single crystal growth in a double-side heater

The effect of heater power control on heat, flow, and oxygen transport for the CCz growth of 8-inch diameter silicon crystal in a triple-crucible was numerically studied. Three different designs of a double-side heater at different power ratios of the lower and upper side heaters (PRSD = 0.25, 1, and 4) were compared with the case of a single-side heater. For the cases considered in the present work, a design in which the upper side heater was shorter than the lower one at PRSD = 0.25 could be a good choice for improving the crystal quality and CCz growth. This was shown by the reductions in the crystal-melt interface deflection and oxygen content and the increase in the melt temperature in the feeding zone. In this case, reducing the interface deflection and crucible bottom wall temperature could enhance the pulling speed. However, the power consumption in this condition was higher than that in the single-side heater case. Achieving a lower heater power was feasible with a higher PRSD value. However, it was important to note that the oxygen content would be higher, and the melt temperature in the outer melt significantly dropped.

Effect of a Self-Assembled Nucleating Agent on the Crystallization Behavior and Spherulitic Morphology of Poly(lactic acid).

Herein, decanedioic acid dibenzoylhydrazide (DDBH) was used as a nucleating agent to improve the crystallization of poly(lactic acid) (PLA). The formation of DDBH assemblies in PLA melts at different concentrations was systematically investigated. The DDBH (0.5-0.9 wt %) recrystallized as dendrite-like structures during the isothermal crystallization process, and the crystal morphology of PLA underwent a morphological change from spherical form to a similar dendritic crystal form. Differential scanning calorimetry and in situ wide-angle X-ray diffraction analysis results showed that crystallizability and overall crystallization rate of PLA were enhanced by the addition of DDBH. The half-crystallization time at 120 °C reduced to 0.28 min compared to pure PLA (6.12 min), after adding 0.9 wt % DDBH. Moreover, the crystallinity and lamellar thickness of crystalline PLA increased, while the size of the microcrystal of PLA decreased with an increase in DDBH content. The heat deflection temperatures of PLA/DDBH blends increased and hence heat resistance improved.

Optimizing rheological performance of unsaturated polyester resin with bio-based reactive diluents: A comprehensive analysis of viscosity and thermomechanical properties

Bio-based reactive diluents (RD) have been explored as alternative to styrene (STY) in unsaturated polyester resin (UPR). Among the different candidates, acrylated epoxidized soybean oil (AESO) and epoxidized linseed oil (ELO) stand out as triglyceride derivatives. Aditionally, methyl methacrylate (MMA), trimethylolpropane triacrylate (TMPTA) with acrylic functionality, limonene (LIM), and cinnamates (CINN), has been tested in different percentages. Firstly, their efficiency in viscosity reduction has been studied. Best results were obtained after the addition of MMA, LIM, and CINN at 5 wt%. These RD achieve a viscosity reduction of 48.9 %, 76.7 %, and 22.9 %, respectively, compared to the reference sample. The industrial utilization of CINN as RD is impeded by its reactivity, as has been evidenced by its prolonged reaction time (24 min) and low reaction enthalpy. The thermo-mechanical properties studied through flexural tests, Shore D hardness, Charpy's Impact test, and heat deflection temperature (HDT), show that the developed UPRs exhibit a decrease in resistant mechanical properties while doubling their ductility by using LIM and MMA as bio-based RD (1.88 and 2.15 kJ m−2, respectively). The HDT study results demonstrate a certain level of thermal stability when MMA is employed (56 °C), which is 15 % lower in the case of LIM. Therefore, it is observed that UPRs with bio-based RD exhibit balanced and improved thermo-mechanical properties in terms of ductility and strength, especially with the use of a 5 wt % of LIM and MMA.

An experimental investigation of flame retardancy and thermal stability of treated and untreated kenaf fiber reinforced epoxy composites

Abstract Natural fiber reinforced polymeric composites perform poor in mechanical and thermal properties at elevated temperatures due to the cellulose and hemicellulose contents of natural fiber start degrading at elevated temperature. In this research work, flame retardancy and thermal stability of treated and untreated kenaf fiber reinforced epoxy composites have been experimentally investigated and reported. Two composite laminates, one with 6 % NaOH Alkali treated and another with untreated woven kenaf mats, were fabricated by hand lay-up technique followed by compression molding with 40 % fiber weight fractions. Flame retardancy test and various thermal characteristics studies such as thermogravimetric analysis (TGA), differential scanning calorimetry (DSC), heat deflection temperature (HDT), and morphological analysis via scanning electron microscopy (SEM) tests were carried out. The results showed that alkali treated kenaf fiber composite achieved V0 fire retardancy grade. The major weight losses, 86 % and 75.5 % for untreated and treated composites respectively were recorded between 300 °C and 450 °C. 13.6 % increase in HDT was noted for treated composite with 0.25 mm deflection at 0.45 MPa pressure condition. Thus the composite laminate with 6 % NaOH alkali-treated kenaf fiber achieved the best thermal stability with less degradation which is more suitable for automobile and aerospace applications.

Effect of MWCNT Anchoring to Para-Aramid Fiber Surface on the Thermal, Mechanical, and Impact Properties of Para-Aramid Fabric-Reinforced Vinyl Ester Composites

In the present work, para-aramid fabrics (p-AF) were physically modified via an anchoring process of 0.05 wt% MWCNT to the aramid fiber surfaces by coating the MWCNT/phenolic/methanol mixture on p-AF, and then by thermally curing phenolic resin of 0.01 wt%. Para-aramid fabric-reinforced vinyl ester (p-AF/VE) composites were fabricated using p-AF/VE prepregs by compression molding. The effect of MWCNT anchoring on the thermo-dimensional, thermal deflection resistant, dynamic mechanical, mechanical, and impact properties and the energy absorption behavior of p-AF/VE composites was extensively investigated in terms of coefficient of linear thermal expansion, heat deflection temperature, storage modulus, tan δ, tensile, flexural, and Izod impact properties and a drop-weight impact response. The results well agreed with each other, supporting the improved properties of p-AF/VE composites, which were attributed to the effect of MWCNT anchoring performed on the aramid fiber surfaces.

Synthesis and Characterization of High Glycolic Acid Content Poly(glycolic acid-co-butylene adipate-co-butylene terephthalate) and Poly(glycolic acid-co-butylene succinate) Copolymers with Improved Elasticity.

Poly(glycolic acid) (PGA) is a biodegradable polymer with high gas barrier properties, mechanical strength, and heat deflection temperature. However, PGA's brittleness severely limits its application in packaging, creating a need to develop PGA-based copolymers with improved elasticity that maintain its barrier properties and hydrolytic degradability. In this work, a series of PGBAT (poly(glycolic acid-co-butylene) adipate-co-butylene terephthalate) copolymers containing 21-92% glycolic acid (nGA) with Mw values of 46,700-50,600 g mol-1 were synthesized via melt polycondensation, and the effects of altering the nGA on PGBAT's thermomechanical properties and hydrolysis rate were investigated. Poly(glycolic acid-co-butylene succinate) (PGBS) and poly(glycolic acid-co-butylene terephthalate) (PGBT) copolymers with high nGA were synthesized for comparison. DSC analysis revealed that PGBAT21 (nGA = 21%) and PGBAT92 were semicrystalline, melting between 102.8 and 163.3 °C, while PGBAT44, PGBAT86-89, PGBT80, and PGBS90 were amorphous, with Tg values from -19.0 to 23.7 °C. These high nGA copolymers showed similar rates of hydrolysis to PGA, whereas those containing <50% GA showed almost no mass loss over the testing period. Their mechanical properties were highly dependent upon their crystallinity and improved significantly after annealing. Of the high nGA copolymers, annealed PGBS90 (Mw 97,000 g mol-1) possessed excellent mechanical properties with a modulus of 588 MPa, tensile strength of 30.0 MPa, and elongation at break of 171%, a significant improvement on PGA's elongation at break of 3%. This work demonstrates the potential of enhancing PGA's flexibility by introducing minor amounts of low-cost diols and diacids into its synthesis.

MC-Injection Molding with Liquid Silicone Rubber (LSR) and Acrylonitrile Butadiene Styrene (ABS) for Medical Technology.

The multicomponent injection molding of liquid silicone rubbers (LSR) with thermoplastics, such as polybutylene terephthalate (PBT) or polyamide (PA), is a state-of-the-art technique and is used in the manufacturing process for many components in the automotive industry and in the field of sanitary engineering. Standard thermoplastics, such as acrylonitrile butadiene styrene (ABS), cannot be bonded with silicone rubbers in injection molding because of their low heat deflection temperature. In this study, we investigated ABS grades approved for medical applications to show how dynamic mold heating and various pretreatment methods for thermoplastic surfaces can be used to produce ABS-LSR test specimens. In addition, such components' sterilization effect on the adhesive bond will be shown.

Biocomposites from poly (butylene succinate-co-butylene adipate) biodegradable plastic and hop natural fiber: Studies on the effect of compatibilizer on performance of the composites

The overall performance of natural fiber reinforced thermoplastic composites is mostly correlated to the fiber-plastic adhesion. Herein, the interfacial adhesion of hop natural fiber (Humulus lupulus) and poly (butylene succinate-co-butylene adipate) (PBSA) bioplastic coupled with an in situ synthesized maleic anhydride grafted PBSA compatibilizer (MA-g-PBSA) was investigated. The fiber was produced by attrition-milling while forced through a mesh of 1 mm and used at 30 weight percent (wt.%) ratio. The developed fiber-matrix adhesion of the coupled biocomposites was confirmed by using scanning electron microscopy (SEM) and supported by mechanical tests. With the use of 5 wt.% MA-g-PBSA, the tensile strength of the biocomposites was comparable to the neat PBSA. But overall, the tensile, flexural, and impact strengths of compatibilized biocomposites improved respectively 45, 16, and 19 % when compared to those uncompatiblized biocomposites. The flexural modulus and the heat deflection temperature were affected by the fiber loading and barely by the coupling agent.

EFFECT OF CELLULOSE NANOFIBERS FROM RED COCONUT PEDUNCLE WASTE AS REINFORCEMENT IN EPOXY COMPOSITE SHEETS

Organic filler-reinforced thermosetting polymer composites, when contrasted with ferrous, nonferrous, and their respective alloys, offer a broad spectrum of applications. Extensive research has been dedicated to enhancing the intrinsic mechanical and thermal properties of composite materials, with a particular focus on environmentally friendly, recyclable, and biodegradable reinforcements. As a result, the present study involved the preparation of composites by amalgamating cellulose nanofibers (CNFs) sourced from agricultural waste with epoxy to augment the characteristics of polymer composites. The CNFs-reinforced epoxy composites were fabricated via the compression molding process, incorporating filler loadings ranging from 1% to 3% by weight. A comprehensive experimental investigation was conducted on the mechanical properties (tensile, flexural, impact, and hardness) and thermal properties (heat deflection temperature) of these composites. Additionally, scanning electron microscopy was employed to examine the surface characteristics and fractured surfaces of the composites. The results revealed that, among the produced composites, those containing 2 wt% CNFs in the epoxy exhibited superior mechanical properties, outstanding tensile and flexural strengths of 42.8 ± 2 MPa and 106.1 ± 1.6 MPa, respectively, along with an impact strength of 13 ± 2.5 KJ/m² and a hardness rating of 21.2. Notably, these 2 wt% CNFs-reinforced epoxy composites exhibited a 7% increase in the heat deflection temperature, compared to the pristine epoxy resin.

Modeling and Design Enhancement of Electrothermal Actuators for Microgripping Applications

Microgrippers are miniature tools that have the capability to handle and manipulate micro- and nano-scale objects. The present work demonstrates the potential impact of the incorporation of perforations on a ‘hot and cold arm’ electrothermal actuation mechanism in order to improve the operation of microgrippers in terms of arm opening and operating temperature. By applying a voltage to one arm and setting the other as a ground, the current passes through the electrothermal actuator and induces its displacement along the in-plane direction. The difference in the geometry of the two arms causes one arm to expand more than the other and this results in transverse bending. A computational model was developed using a finite element analysis tool to simulate the response of the thermal actuators with varying geometries and investigate the impact of incorporating perforations on the arms of the thermal actuators to enhance its performance in terms of deflection and operating temperature. The simulation results were compared to their experimental counterparts reported in the literature. A good agreement between the numerical and experimental data was obtained. A novel design of a microgripper, made of perforated electrothermal actuators, was introduced. Its main characteristics, including the tip opening of the gripper arms, the applied voltage, and the stress and temperature distributions, were analyzed using the developed computational model. Different perforation shape and distribution were investigated. The present study demonstrates the capability of perforations to enhance the operation of microgrippers as manifested by the obtained higher tip displacement and lower tip temperature in comparison to conventional microgripper designs made of non-perforated thermal actuators. Furthermore, the highest stress generated on the microgripper elements was found to be much lower than the yield strength of the constituent material, which indicates proper functioning without any mechanical failure.

Recycling of poly(lactic acid)/poly(butylene succinate) (PLA/PBS) blends with high amounts of secondary raw material

AbstractIn this study, the mechanical recycling of poly(lactic acid)/poly(butylene succinate) (PLA/PBS)‐based formulations with additives was investigated. A simulation of mechanical recycling was performed using secondary raw materials in the analyzed formulations (at very high levels &gt;30%). The recycling process was simulated by repeating extrusion cycles on the compound to produce aging under accelerated conditions, similar to those that normally occur during the extrusion compounding of the bioplastic material. The formulations were characterized by using differential scanning calorimetry (DSC), heat deflection temperature (HDT), melt flow rate (MFR), Fourier transform infrared spectroscopy (FTIR) and UV–vis spectroscopy. The aim of the work was to study the efficiency of a multi‐epoxy chain extender in mechanical recycling of PLA/PBS blends. The results showed that the use of secondary raw materials did not cause drastic changes in the thermal properties and chemical composition of the blends, which indicates that they are suitable for manufacturing bioplastic blends. Specifically, MFR results showed a major efficiency of the chain extender in samples having PLA as primary polymeric phase, whereas no change was observed in formulations where PBS is the main phase with the addition of a higher amount of chain extender.

3D Printing of sustainable coal polymer composites: Thermophysical characteristics

Recently, there has been a growing interest in enlisting polymer-based additive manufacturing in high-volume structural applications such as wind turbine blade tooling and additive housing construction. However, the availability of sustainable and environmentally friendly 3D printable materials could present a serious challenge, precluding the technology expansion to such applications. This research was focused on developing sustainable and environmentally friendly coal-plastic composites for use in high-volume applications. Polylactic acid, polyethylene terephthalate glycol, high-density polyethylene, and polyamide-12 resins were melt-mixed with bituminous Pittsburgh No. 8 coal at loadings varying from 20 wt % to 70 wt % coal. Thermoplastic composite filaments were extruded and processed with commercial 3D printers. Important thermophysical properties including coefficients of thermal expansion, heat deflection temperatures, glass transition and melt temperatures, specific heat capacities, thermal conductivities, and thermal stabilities of the coal-plastic composites were investigated. Coefficient of thermal expansion values for the composites had an inverse relationship with coal content lending to decreased print warping and consistent 3D printing of high-density polyethylene materials. Coal increased the heat deflection temperature of high-density polyethylene composites while little to no effect was observed for the other plastics. All composites maintained comparable melt temperatures, allowing for processing with commercial equipment. Specific heat capacity and thermal conductivity decreased with coal loading for all composite materials. Thermogravimetric analysis under air showed that the introduction of coal improved the thermal stability of all plastics by increasing the decomposition temperatures at 5 % and 50 % weight loss and by reducing the maximum decomposition rates.

Tailoring PLA/ABS Blends Compatibilized with SEBS-g-MA through Annealing Heat Treatment.

In this work, blends based on poly (lactic acid) (PLA)/acrylonitrile-butadiene-styrene (ABS) compatibilized with maleic anhydride-grafted (SEBS-g-MA) were prepared in a co-rotational twin-screw extruder by varying the concentrations of the compatibilizing agent. The influence of the compatibilizing agent on the morphology, mechanical, thermal, thermomechanical, and rheological properties of the prepared materials was analyzed. The effect of annealing on the properties of the blends was also investigated using injection-molded samples. The X-ray diffraction (XRD) results proved that the increments in crystallinity were an effect of annealing in the PLA/ABS/SEBS-g-MA blends, resonating at higher heat deflection temperatures (HDTs). The impact strength of the PLA/ABS blends compatibilized with 10 wt% SEBS-g-MA was significantly increased when compared to the PLA/ABS blends. However, the hardness and elastic modulus of the blends decreased when compared to neat PLA. The refined morphology shown in the scanning electron microscopy (SEM) analyses corroborated the improved impact strength promoted by SEBS-g-MA. The torque rheometer degradation study also supported the increased compatibility between SEBS-g-MA, PLA, and ABS. The TGA results show that the PLA/ABS and PLA/ABS/SEBS-g-MA blends are more thermally stable than the neat PLA polymer at higher temperatures. The results showed that the ideal composition is the heat-treated PLA/ABS/SEBS-g-MA (60/30/10 wt%), given the high impact strength and HDT results. The results of this work in terms of mechanical improvement with the use of compatibilizers and annealing suggest that the PLA/ABS/SEBS-g-MA system can be used in the production of 3D-printing filaments.
