Optimization of chemical treatment process parameters for enhancement of mechanical properties of Kenaf fiber-reinforced polylactic acid composites: A comparative study of mechanical, morphological and microstructural analysis

As advancements in sustainable material science continue, kenaf fiber and polylactic acid (KF/PLA) composites have emerged as promising eco-friendly alternatives. The current research article has focused on improving the physical strength of these KF/PLA composites. Methodologies like Taguchi's and Grey Relational Analysis (GRA) have been employed to identify the most effective ways to enhance the chemical treatment process. The composites were manufactured using an injection molding technique while essential variables were modified. These variables comprised the choice of chemical treatments (sodium hydroxide, potassium hydroxide, or sodium acetate), the concentration of these chemicals (1%, 2%, or 3% w/v), and the duration of treatment (2, 4, or 6 h). These modifications led to the production of diverse KF/PLA composite variants. The physical strength of these modified composites was evaluated using various methods, focusing on their tensile strength, tensile modulus, elongation under tension, flexural strength, flexural modulus, deformability under bending, and impact resistance. A Scanning Electron Microscope (SEM) was utilized to observe the treated and tested samples in detail. The optimal values identified through GRA and mean plots were same for the composite. Improved mechanical properties of KF/PLA were observed when the optimal conditions of A1-B2-C2 (NaOH, 2%, and 4 h) were applied. Although, the morphology of the PLA matrix-based bio composites reinforced with kenaf fiber with different surface-treatments was recorded using AFM analysis in order to further reveal the surface roughness of fibers upon surface modification and dispersion.

The Bhimal fiber, derived from agro-waste and found in abundant Himalayan forest is having no commercial utilization and economical contribution to the state yet while it possess superior mechanical properties. This study explores the novel idea of utilizing bhimal fiber, and the interaction of agro-industrial wastes, resulting in will improve the economy of the farmers and the state. The bio composites were created by incorporating different types of industrial-waste particulates, including CaCO3, Flyash, and TiO2, at varying weight percentages with 15% and 20% by weight of Bhimal fiber. NaOH-treated Bhimal fiber was cast-off for improving to surface structure of native cellulose and resulting in enhancement of the mechanical properties of the biocomposites. The study found that the incorporation of CaCO3/Flyash/TiO2 at 5, 10, and 15 Weight (wt.)% with 20 and 15 wt% of Bhimal-fiber enhanced the properties of developed biocomposites. Incorporation of TiO2 at 5 wt% leads to a significant improvement in tensile and compressive strength along with hardness, by 122.26%, 103.02%, and 73.54%, respectively. The flexural strength decreased with increasing percentages of CaCO3/TiO2 (from 5 to 15 wt%), while fly-ash incorporation at 5, 10, and 15 wt% led to an increase in flexural strength, with a maximum increase of 135.06% at 15 wt% fly-ash, and an increase in impact strength of 295.51% at 10 wt% of fly-ash. The incorporation of nano-TiO2 resulted in lowest porosity by 13.22% and higher thermal stability. The study concluded that Nano-TiO2 is the most effective filler for reinforcing the bio composite.

Additionally, the study measured the diffusion coefficient of bio composites, which had a minimum value of about 2.11 × 10−6mm2/s and a maximum value of about 3.99 × 10−6mm2/s. The results of RSM model analysis showed that this model is accurate and reliable. Where the values of R2 and adjusted R2 coefficients for the Mass of CDPF were 99.63 % and 99.61 %, respectively, indicating an ideal match between experimental and predicted values. These findings provide valuable information for engineers interested in incorporating date palm fiber bio composites during development and implementation.

Bio composite of porous hydroxyapatite and collagen extracted from eggshell membrane and Oreochromis niloticus fish skin for bone tissue applications

AbstractPorous hydroxyapatite (HA) was prepared by a chemical reaction between eggshell and phosphoric acid mixed with a foaming agent. Hydroxyapatite was composited with collagen prepared from a fermentation process of Acetobacter xylinum with eggshell membranes, extraction process of Oreochromis niloticus fish skin, and commercial‐grade collagen.

Free vibration analysis was conducted to determine important characteristics like damping frequency, damping ratio, and natural frequency of the bio composites. The resonant set obtained for Sisal/PLA is inferior to Jute/PLA composites, which clearly demonstrates the influence of fibre in resonant behaviour of the composites. Further Sisal/PLA composites show 20% rise in damping performance at first two resonant sets and 30% in the third resonant. This free vibration characterization of most widely used to composites provides valuable insights into the practical usage under suitable environment conditions.

Comprehensive characterization of 3D‐printed bamboo/poly(lactic acid) bio composites

AbstractIn recent years, the use of additive manufacturing technologies especially fused deposition modeling (FDM), 3D printing, have been raised popularity. Poly(lactic acid) (PLA) is one of the most widely used materials in FDM because it is suitable for biodegradation due to environmental problems. Therefore, to improve the properties of PLA and extend its lifespan, the material to be added to its structure must be of natural origin. In this study, mechanical, thermal, thermo‐mechanical, tribological, and morphological properties of composite materials manufactured using bamboo filled PLA filament by FDM method were investigated. The thermal properties of the samples were investigated by differential scanning calorimeter analysis, thermomechanical properties by dynamic mechanical thermal analysis, mechanical properties by tensile and three‐point bending test, and surface hardness by Shore D test. Since there are few studies in the literature examining the effects of 3D printing parameters on tribological properties, in this study, various layer thicknesses, top/bottom pattern, specimen face, and build plate surface type on the wear behavior were examined. Worn surfaces and fractured surfaces were investigated by SEM.

The deliberation of the environmental effect on synthetic polymer products has effectuated the development of the latest materials obtained from natural resources. This work tested the compatibility of a bio composite of polyvinyl alcohol (PVA) and cellulose. The mechanical effect of cellulose on PVA was investigated in the Synthia module of BIOVIA material studio and Artificial neural network. The exacted shear and bulk modulus were obtained with the variation of mass fraction of cellulose from 0 to 1 mass%. At 1% mass fraction of cellulose, the mechanical properties of PVA like shear modulus and bulk modulus had increased to 401% and 130%, respectively. The dry lab values of shear and bulk modulus were further analysed through a Bi-layer Artificial Neural Network (ANN). The designed ANN successfully predicted the bulk and shear modulus values. The implemented ANN prevailed with a root mean square error of 2.0692 and 1.865 for both properties.

Synthesis of a chitosan@hydroxyapatite composite hybrid using a new approach for high-performance removal of crystal violet dye in aqueous solution, equilibrium isotherms and process optimization

BackgroundNovel chitosan and hydroxyapatite-based bio composites were studied as potential adsorbents for the removal of crystal violet, a cationic dye, present in an aqueous solution employing various experimental metrics such as initial concentration, pH, adsorbent mass, contact time, temperature, and effect of agitation. MethodsThe biosorbent was analyzed by several techniques such as Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), scanning electron microscopy (SEM), specific surface by BET theory, thermal analysis ATG and X-ray energy dispersal (EDS). Significant FindingsThe present study focuses on the synthesis of chitosan, a polymer extracted from shrimp shells, and its association with synthesized hydroxyapatite to form a Cs@Hap composite effective for the adsorption of a cationic dye, crystal violet. The physical and functional properties of the composite were studied using several techniques. X-ray diffraction confirmed the formation of the composite by its crystalline structure, infrared analysis revealed the presence of NH, OH and PO functional groups responsible for the adsorption, SEM coupled with EDS as well as BET and ATG allowed to characterize the surface of the composite as porous, rough and heterogeneous, with an SSA of 138.47 m2g−1, perfect for the adsorption of the given dye. The resulting adsorption efficiency is high and was able to reach a maximum of 93.21% through the optimization of the parameters affecting the adsorption, namely an adsorbent mass of 0.1 g at a pH value equal to 6.5. The kinetic, isothermal and thermodynamic study showed that the adsorption was endothermic and follows the pseudo-second order and Redlich-Peterson models. The regression coefficient R²= 0.9219 showed the validity of the response surface methodology coupled to the Box Behnken design (RSM-BBD) in predicting the percent removal of CV by adsorption.

Development of hybrid composite with natural fillers for mechanical property and machinability study

The urge to build a more environmentally friendly future has motivated researchers to examine composites outside of synthetic fiber and continue to consider natural fibre polymer composite. This present research, the hybrid bio composite was developed by bio fillers and natural fibres. The preliminary investigation was done to examine the possibility of using natural fillers (palm and coconut shell) in natural fibre (hemp and basalt) reinforced polymer (NFRP) composite for manufacturing application. In that way initially mechanical (tensile and flexural) properties testing were done on four different combinations of NFRP by using palm and coconut shell particles, to their influence on mechanical properties (tensile stress 278 MPa and flexural stress 330 MPa). It was found that 5% wt. palm + coco shell fillers combination hybrid composite presented good results in mechanical properties. Then 5% wt. palm + coco fillers was added in the matrix phase of NFRP composite was developed and study the machinability properties by using Abrasive Water Jet Machining (AWJM). NFRP machining in the relationships of material removal rate (MRR), kerf angle and surface roughness has been experimentally examined for various process parameters (nozzle pressure, distance stand and transverse speed). The research values for quality properties (MRR, Kt and Ra) were analysis-based on the trimming factors by developing the Taguchi method. The influence of optimized input process parameters on quality features were examined by utilizing experiential models. From this study, it is noticeable that, filler material in natural fiber composites reduces the kerf angle and the low and very high traverse speed leads the wide disparity in kerf inclination. For obtaining the good surface roughness and material removal rate medium traverse speed and medium stand of distance is the significant parameter respectively and moreover impact of jet pressure on surface finish is 3 times lower than the impact supplied to the surface finish by traverse speed

Comparative study of FESEM, EDS, FTIR on alkali treated and untreated fiber of Aerva

The Amaranthaceae family plant, Aerva Tomentosa, grows abundantly in western Rajasthan, India. In the production of bio composites, the Aerva Tomentosa (Bui) can be used successfully as natural fibers. In this study, Aerva Tomentosa (Bui) fibers were extracted from the Bui plant and treated with an alkaline solution containing 5% NaOH. The investigation involved morphological and chemical characteristics of the extracted untreated Aerva Tomentosa fibers (ATF(0)) and extracted alkali treated Aerva Tomentosa fibers (ATF(1)). According to an analysis of ATF(0) and ATF(1) using Fourier-transform infrared (FTIR) spectroscopy, both ATF(0) and ATF(1) included functional groups for cellulose, hemicellulose, and lignin. The elimination of extractives from the surface of the fibers isolated from Aerva tomentosa is demonstrated by FESEM and EDS analysis. The surface of untreated fibers becomes smoother following treatment, as evidenced by FESEM images taken at various resolutions.

Performance of novel pillared eggshell-bentonite clay bio-composite for enhanced phosphate adsorption from aqueous media

Modified clay mineral is a potential technique for phosphorus adsorption and has received much attention in the high phosphate pollution witnessing regions. In the present work, an iron-pillared eggshell-modified bentonite clay bio composite (IP-ESMB) is used to test the adsorption of phosphate from the aqueous medium. The characteristics of the prepared IP-ESMB bio composite were analyzed using XRF, SEM, EDX, FTIR, XRD, BET, TG and DTG analysis to study its physicochemical characteristics. The diffusion process, electrostatic interaction, and ion exchange mechanisms work in concert to remove the phosphate ions effectively at a pH of 3.0. The adsorption capacity is influenced by the initial phosphate concentrations, adsorbent dose (2 g/L), contact time (50 min), temperature (303 K) and pH (3.0) of the solution. Kinetic studies revealed that the pseudo-second-order model best described the experimental data. The Langmuir isotherm model provided the best fit for the equilibrium isotherm data of the IP-ESMB, and the determined Q0 value was found to be 60.51 mg/g at pH 3.0 and 30 0C. The reaction was endothermic and spontaneous, according to thermodynamic analysis, with overall changes in enthalpy (ΔH0) and entropy (ΔG0) of 10.08 KJmol-1 and 0.09 KJmol−1K−1, respectively. It is also found that the IP-ESMB bio composite has excellent reusability over several adsorption cycles. Designing an adsorption reactor provides another means of calibrating the performance of the created bio-composite during factorial operations. This study confirms that to curb eutrophication in a natural water system, the present modified clay mineral can efficiently act as a green adsorbent.

Short Flax Fibres and Shives as Reinforcements in Bio Composites: A Numerical and Experimental Study on the Mechanical Properties.

The complete flax stem, which contains shives and technical fibres, has the potential to reduce the cost, energy consumption and environmental impacts of the composite production process if used directly as reinforcement in a polymer matrix. Earlier studies have utilised flax stem as reinforcement in non-bio-based and non-biodegradable matrices not completely exploiting the bio-sourced and biodegradable nature of flax. We investigated the potential of using flax stem as reinforcement in a polylactic acid (PLA) matrix to produce a lightweight, fully bio-based composite with improved mechanical properties. Furthermore, we developed a mathematical approach to predict the material stiffness of the full composite part produced by the injection moulding process, considering a three-phase micromechanical model, where the effects of local orientations are accounted. Injection moulded plates with a flax content of up to 20 V% were fabricated to study the effect of flax shives and full straw flax on the mechanical properties of the material. A 62% increase in longitudinal stiffness was obtained, resulting in a 10% higher specific stiffness, compared to a short glass fibre-reinforced reference composite. Moreover, the anisotropy ratio of the flax-reinforced composite was 21% lower, compared to the short glass fibre material. This lower anisotropy ratio is attributed to the presence of the flax shives. Considering the fibre orientation in the injection moulded plates predicted with Moldflow simulations, a high agreement between experimental and predicted stiffness data was obtained. The use of flax stems as polymer reinforcement provides an alternative to the use of short technical fibres that require intensive extraction and purification steps and are known to be cumbersome to feed to the compounder.

Sol-Gel Synthesis of New TiO2 Ball/Activated Carbon Photocatalyst and Its Application for Degradation of Three Hormones: 17α-EthinylEstradiol, Estrone, and β-Estradiol.

Many approaches have been investigated to eliminate pharmaceuticals in wastewater treatment plants during the last decades. However, a lack of sustainable and efficient solutions exists for the removal of hormones by advanced oxidation processes. The aim of this study was to synthesize and test new photoactive bio composites for the elimination of these molecules in wastewater effluents. The new materials were obtained from the activated carbon (AC) of Arganian spinosa tree nutshells and titanium tetrachloride by the sol gel method. SEM analysis allowed one to confirm the formation of TiO2 particles homogeneously dispersed at the surface of AC with a controlled titanium dioxide mass ratio, a specific TiO2 anatase structure, and a highly specific surface area, evidenced by ATG, XRD, and BET analysis, respectively. The obtained composites were revealed to quantitatively absorb carbamazepine (CBZ), which is used as a referred pharmaceutical, and leading to its total elimination after 40 min under irradiation with the most effective material. TiO2 high content disfavors CBZ adsorption but improves its degradation. In the presence of the composite, three hormones (17α-ethinylestradiol, estrone, and β-estradiol) are partially adsorbed onto the composite and totally degraded after 60 min under UV light exposure. This study constitutes a promising solution for the efficient treatment of wastewater contaminated by hormones.
