A functional lignin-based nanofiller for flame-retardant blend

Lignin-based flame retardants represent great promising next-generation flame retardants due to their sustainability, unique aromatic structure, and high charring capability. However, their applications are still limited by the compatibility, processability, and efficiency of flame retardancy. Here, a green functional lignin-based nanofiller (lignin-diethylenetriamine/red phosphorus nanoparticles, Lignin-N-P NPs) was prepared by the chemical modification and co-precipitation. After blending with the commercial acrylonitrile butadiene styrene copolymers (ABS), the physical, chemical, and flame retardant properties of the blends reveal that Lignin-N-P NPs/ABS blend has acceptable processability, mechanical properties, and significantly improved thermal stability and fire performance. Its values of peak heat release rate and total heat released per unit area were significantly dropped 67.8% and 77.5%, respectively. This study will initiate a new design for not only flame retardants but also lignin-based materials.

Composition Analysis of Grafted ABS and its Blend Copolymers Using a Combination of 1H NMR Spectroscopy and Nitrogen Element Analysis

The composition analysis of the acrylonitrile butadiene styrene (ABS) copolymer was performed using a method combining elemental analysis and 1H nuclear magnetic resonance (NMR) spectroscopy. The physicochemical properties of ABS are determined by the relative contents of the constituent monomers. However, because ABS undergoes a complicated microstructural change during the polymerization process, it is difficult to accurately analyze the relative contents using only a typical method. In this study, a combination of nitrogen elemental analysis and 1H NMR spectroscopy was proposed as an analytical method that can consider the effects of changes in the microstructures. This approach confirmed whether the ABS samples were close to meeting the specifications. In addition, the composition analyses of polylactic acid/ABS blends, polycarbonate/ABS blends, and a polyamide 6/ABS mixture sample indicate that the obtained results were consistent with the expected values, thereby demonstrating that this combined analytical approach can be applied to various types of ABS copolymer systems.

The Influence of Graphene Nano-Sheets Inclusion on the Mechanical and Thermal Characteristics of Acrylonitrile–Butadiene–Styrene Copolymer

Graphene nano-sheets (GNS) and acrylonitrile butadiene styrene (ABS) were combined with various GNS inclusion quantities. The influence of GNS on the thermal, mechanical, electrical, and fireproofing characteristics of ABS-GNS composites have been researched. With the inclusion of 3.0 wt% GNS, the hardness, Young's Modulus, elastic modulus, bending strength, bending modulus, storage modulus, and conductivity of the ABS-GNS composites enhanced by 1647%, 21%, 37%, 19%, 70%, 43%, and 900% correspondingly. Moreover, the cone calorimeter and TGA-DTG test results showed significant thermal strength, and flame-resistant characteristics were induced on the ABS-GNS composites. These improved characteristics are associated with the appropriate spread and close contact of GNS and ABS structure as verified with the electron microscopy outcome.

Rheological Measurements and Structural Analysis of Polymeric Materials.

Rheological measurements of polymer melts are widely used for quality control and the optimization of processing. Another interesting field of rheology is to provide information about molecular parameters of polymers and the structure build-up in heterogeneous polymeric systems. This paper gives an overview of the influence of molar mass, molar mass distribution and long-chain branching on various rheological characteristics and describes the analytical power following from established relations. With respect to applications, we discuss how rheological measurements can be used to gain insight into the thermal stability of a material. A special impact lies in the demonstration, how long-chain branching can be analyzed using rheological means like the zero-shear viscosity as a function of molar mass and strain hardening occurring in elongation. For contributions to branching analysis, the thermorheological behavior and activation energies are particularly discussed. The use of elastic quantities in the case of mechanical pretreatment effects is briefly addressed. The influence of fillers on recoverable properties in the linear range of deformation is analyzed and the role of their specific surface area for interactions described. It is shown how the fundamental results can be applied to study the state of nanoparticle dispersions obtained under special conditions. Furthermore, it is demonstrated that the findings on polymer/filler systems are the base of structure analyses in heterogeneous polymeric materials like polyvinylchloride (PVC) and acrylonitrile–butadiene–styrene copolymers (ABS).

Acoustic cloak designed by topology optimization for acoustic–elastic coupled systems

By including acoustic-elastic interactions in a topology optimization based on the covariance matrix adaptation evolution strategy, we developed acoustic cloaks of optimal design that render an object unobservable through airborne and water-borne sounds. This strategy helps in exploring optimal topologies that minimize the scattering of airborne and water-borne sounds around acoustic cloaks made from acrylonitrile butadiene styrene copolymers frequently used as ink in 3D printers. By applying level set methods, our designed cloaks are expressed as iso-surfaces representing the sharp structural boundaries between the acoustic and elastic media. On these boundaries, conditions that couple the elastic and acoustic aspects of the scattering are imposed. Furthermore, our cloak designs ensure that scatterers are unobservable to sound waves of multiple frequencies incident from various angles by minimizing the fitness incorporating multiple objective functions under several structural symmetries.

Evaluation of the applicability of polymeric materials to BTEX and fine product transformation by catalytic and non-catalytic pyrolysis as a part of the closed loop material economy

This article presents experimental results on the pyrolysis of different mixtures of polymer waste. ABS copolymer, PET, PP, tire waste styrene-butadiene rubber (SBR) and pure non-vulcanised SBR were used in the experiments under different catalyst conditions: (i) without a catalyst, (ii) with an unmodified ZSM-5 catalyst, (iii) with a ZSM-5 catalyst possessing ammonium groups, and (iv) with a ZSM-5 catalyst containing 10 % Ni. The primary objective of this study was to select suitable conditions to pyrolyse polymeric materials depending on the polymer type and properties of the desired final products, e.g., aromatic and heteroaromatic hydrocarbons and valuable chemical subproducts.Suitable conditions can be determined for the thermal conversion of polymeric materials, and using non-catalytic pyrolysis can yield chemical compounds such as alpha-methyl styrene from acrylonitrile-butadiene-styrene (ABS) and limonene from tire waste, which can be used in both fine chemicals and industrial production. The pyrolysis conditions can be modified in terms of the catalyst based on the tested waste polymer and result in products rich in BTEX fractions.Among all tested catalysts, the ZSM-5 catalyst based on aluminosilicate impregnated with nickel ions yielded the highest total fraction of aromatic and heteroaromatic hydrocarbons, especially from the pyrolysis of PP and PET. With this catalyst, more than 75 area% of the product stream (of the total identified product peaks by MS) consisted of aromatic and heteroaromatic fractions (e.g., terephthalonitrile from polyethylene terephthalate), which were composed of 5.6 and 19.9 area% benzene, 7.0 and 10.8 area% toluene, 5.7 and 10.6 area% ethylbenzene and 1.2 and 1.4 area% xylene for PP and PET, respectively. High proportions of the aromatic and heteroaromatic fractions were observed in the product stream during the ABS pyrolysis with two types of catalysts: aluminosilicate with ammonium groups (73 area% of the aromatic and heteroaromatic hydrocarbons) and aluminosilicate impregnated with nickel ions (85 area% of the aromatic and heteroaromatic hydrocarbons).

Multifunctional graphene-based nano-additives toward high-performance polymer nanocomposites with enhanced mechanical, thermal, flame retardancy and smoke suppressive properties

Despite many important industrial applications, the acrylonitrile–butadienestyrene copolymer (ABS) suffers from an inherent flammability, extremely hampering its practical use. Current flame retardants can effectively reduce the flammability issue but give rise to degraded mechanical and thermal properties of ABS. To address this intractable challenge, a graphene-derived flame retardant (Mo5/PN-rGO) was designed by introducing the functional elements (phosphorus, nitrogen and molybdate) onto the graphene oxides nanosheets. The resultant ABS nanocomposite containing 1.0 wt% of Mo5/PN-rGO exhibits a 28% increase in the tensile strength and a 58% enhancement in the Young’s modulus as compared to the ABS host. Furthermore, the glass transition temperature (Tg) increases by ca. 12 °C while the onset thermal decomposition temperature is significantly delayed by ca. 21 °C. In addition, the final ABS nanomaterial shows a 20% reduction in the total heat release and a 45% decrease in the total smoke production in comparison to the ABS bulk. This work paves a new way for the creation of high-performance flame retardants towards advanced flame-retardant polymer nanocomposites with expandable industrial applications.

Functionalisation of multiwalled carbon nanotubes with melamine phosphate and their influence on morphology, thermal stability, flame retardancy and mechanical properties of ABS

ABSTRACT Multiwalled carbon nanotubes (MWCNTs) were carboxylated by nitric acid oxidation/plasma pretreatment, and melamine phosphate (MP) was grafted onto the surface of MWCNTs to obtain functionalised MWCNTs-MP. The modified MWCNTs were characterised by FT-IR, Raman spectroscopy, XRD, 1H-NMR, TEM, SEM and TGA. The results proved the successful preparation of MWCNTs-MP. The acrylonitrile–butadiene–styrene copolymer (ABS) composites were prepared by melt blending with MWCNTs-MP and characterised using TGA, microscale combustion calorimeter, limiting oxygen index (LOI), SEM and tests to record mechanical properties. The addition of 1% MWCNTs-MP to ABS improved its thermal stability, reduced combustion parameters and increased its LOI value by 27.8%. This is attributed to the MP grafted onto the surface of the MWCNTs. During combustion, this forms a char layer that acts as a heat transfer barrier. The enhanced mechanical properties of the composite were attributed to the improved dispersion of the modified MWCNTs-MP in ABS.

Cancer and non-cancer health risk assessment of occupational exposure to 1,3-butadiene in a petrochemical plant in Iran.

1,3-Butadiene is classified as carcinogenic to humans by inhalation. This study aimed to assess cancer and non-cancer risk following occupational exposure to 1,3-butadiene. This cross-sectional study was conducted in a petrochemical plant producing acrylonitrile butadiene styrene copolymer in Iran. Occupational exposure to 1,3-butadiene was measured according to the National Institute for Occupational Safety and Health 1024 method. Cancer and non-cancer risk assessment were performed according to the United States Environmental Protection Agency method. The average occupational exposure to 1,3-butadiene during work shifts among all participants was 560.82 ± 811.36 µg m-3. The average lifetime cancer risk (LCR) in the present study was 2.71 × 10-3; 82.2% of all exposed workers were within the definite carcinogenic risk level. Also, the mean non-cancer risk (hazard quotient (HQ)) among all participants was 10.82 ± 14.76. The highest LCR and HQ were observed in the safety and fire-fighting station workers with values of 7.75 × 10-3 and 36.57, respectively. The findings revealed that values of carcinogenic and noncarcinogenic risk in the majority of participants were within the definitive and unacceptable risk levels. Therefore, corrective measures are necessary to protect these workers from non-cancer and cancer risks from 1,3-butadiene exposure.

Tailoring physico-mechanical properties and rheological behavior of ABS filaments for FDM via blending with SEBS TPE

PurposeThis paper aims to focus on the development of the three-dimensional (3D) printing filaments based on acrylonitrile butadiene styrene (ABS) copolymer and styrene-ethylene/butylene-styrene (SEBS) block copolymer, with tailored viscoelastic properties and controlled flow during the 3D printing process.Design/methodology/approachIn this investigation, ABS was blended with various amounts of SEBS via a melt mixing process. Then the ABS/SEBS filaments were prepared by a single-screw extruder and printed by the FDM method. The rheological properties were determined using an MCR 501 from Anton-Paar. The melt flow behavior of ABS/SEBS filaments was determined. The morphology of the filaments was studied by scanning electron microscope and the mechanical (tensile and impact) properties, surface roughness and void content of printed samples were investigated.FindingsThe rheological results can accurately interpret what drives the morphology and mechanical properties’ changes in the blends. The impact strength, toughness, elongation-at-break and anisotropy in mechanical properties of ABS samples were improved concurrently by adding 40 Wt.% of SEBS. The optimal tensile properties of blend containing 40 Wt.% SEBS samples were obtained at −45°/+45° raster angle, 0.05 mm layer thickness and XYZ build orientation. Optimized samples showed an 890% increase in elongation compared to neat ABS. Also, the impact strength of ABS samples showed a 60% improvement by adding 40 Wt.% SEBS.Originality/valueThe paper simultaneously evaluates the effects of material composition and 3D printing parameters (layer thickness, raster angle and build orientation) on the rheology, morphology, mechanical properties and surface roughness. Also, a mechanical properties comparison between printed samples and their compression-molded counterpart was conducted.

Mathematical design and preliminary mechanical analysis of the new lattice structure: “GE-SEZ*” structure processed by ABS polymer and FDM technology

In this study, the authors propose a new design of a novel class of lattice structures. The new design is based on two main geometrical properties, the “volume” and the “surface to volume ratio”. It takes advantage of the strongest column designed against buckling proposed by Keller (Arch Ration Mech Anal 5:275–285, 1960) and Seiranyan (J Appl Math Mech 51(2):272–275, 1987). The Schoen minimal gyroid is used as a reference to establish the necessary lightweight property of the proposed design. This is to say, the surface to volume ratio and the volume of the new class of structures and their gyroid equivalent are equal. Models are built using CAD software and printed with UP mini 2.0 using acrylonitrile butadiene styrene (ABS) copolymer. Moreover, compression tests are conducted, using “MTS Criterion—Model 45”. The results show that after the phases of elasticity, relaxation and plasticity, the structure (three samples) is stable in the sense that it did not buckle nor collapse. Furthermore, reaching 7.35 mm of platen displacement (14.7% of strain) and 7.5 kN of resistance (3 MPa of equivalent stress), an additional progressive hardening is observed due to material densification and friction phenomena. A normalized comparison between the proposed structure and several lattice structures is conducted, showing a higher competitive behavior of the new design. The results of this study could possibly be a major contribution in the fields of biomechanics, aeronautic, and mechanical parts design.

Synthesis of a novel aluminium salt of nitrogen-containing alkylphosphinate with high char formation to flame retard acrylonitrile-butadiene-styrene.

A novel nitrogen-containing alkylphosphinate salt—aluminium β-(p-nitrobenzamide) ethyl methyl phosphinate (AlNP) was synthesized and used to flame retard acrylonitrile–butadiene–styrene copolymer (ABS). The Fourier transform infrared spectrometry, 1H, 13C and 31P nuclear magnetic resonance and X-ray fluorescent spectroscopy (XRF) were applied to characterize the structure and composition of products. The flame retardancy performance, thermal properties and mechanical strength of the ABS/AlNP with respect to AlNP loading were investigated. AlNP was stable before 330°C and decomposed very slowly with residues high up to 56.1% at 700°C. Adding 25–30 wt% of AlNP alone can make ABS to pass V0 rating in the vertical burning tests (UL 94). The results according to the micro combustion calorimeter, thermogravimetric analysis showed that AlNP can depress the heating release and retard the thermal degradation of the ABS. Scanning electron microscopy observation of the residues from LOI test indicated that AlNP formed the condensed and tough residues layer during combustion; XRF analysis showed that the residues contained phosphorus and aluminium element and nitrogen element was not detected. The compact phosphorus/aluminium-rich substance acted as a barrier to enhance flame-retardant properties of the ABS.

3D printing of semicrystalline polypropylene: towards eliminating warpage of printed objects

Fused filament fabrication (FFF) is an extrusion-based 3D printing technique for thermoplastic polymers. In this technique, molten polymer is extruded through a print nozzle and is laid down layer by layer to build up the printed object. Currently, FFF is used primarily to print amorphous or low-crystallinity polymers, such as acrylonitrile butadiene styrene copolymer (ABS) or polylactic acid (PLA). Printing of semicrystalline polymers, such as polyethylene or polypropylene remains particularly challenging. During FFF of semicrystalline polymers, large thermomechanical stresses are generated when the polymer solidifies on cooling. These stresses result in warpage of the printed part. Here, we analyse the factors that influence stresses generated during FFF 3D printing of a commercial semicrystalline polymer, isotactic polypropylene. We investigate the effect of height of the printed object on part warpage, as well the effect of infilling during printing. We demonstrate that the stresses generated during FFF can be substantially decreased by incorporation of a ‘brim’, viz. a thin layer at the base of the printed object, and by adhering the brim to the print substrate using common polyvinyl acetate-based glue. We systematically investigate the effect of the brim size on the warpage of the printed object. We support our experimental findings with finite element method (FEM) simulations that explain the mechanism of stress buildup during printing. The trend in stresses calculated in the FEM simulations parallel the warpage measured in the experiments. Thus, this work represents an important methodological advance towards warpage-free FFF printing of semicrystalline polymers.

Effects of auxiliary heat on warpage and mechanical properties in carbon fiber/ABS composite manufactured by fused deposition modeling

Fused Deposition Modeling (FDM) technology offers opportunities for high-efficiency design and low-cost manufacturing of 3D complex parts in additive manufacturing (AM). The warpage remains a big problem which prevents the industrial application of FDM parts, especially parts fabricated by fiber-reinforced composite. In this study, an auxiliary heating plate was developed and mounted on the printing head of an FDM 3D printer to suppress the warpage of the parts made with short carbon fiber (CF)-reinforced acrylonitrile-butadiene-styrene copolymers (ABS) composites. It is found that auxiliary heating and raster angle of FDM process are the two dominating parameters on the tensile properties and the warpage of FDM parts. For the best parameter combination, 160 oC for auxiliary heating temperature and 0 degree for raster angle, the warpage was completely suppressed and the tensile strength got 31% enhancement, ductility got 439% enhancement compared to the FDM part without auxiliary heating and 0 degree in raster angle. Cyclic fatigue behavior and anisotropy of CF/ABS specimen was also significantly improved by auxiliary heating treatment. The reduced stain caused by the annealing ability of auxiliary heating during the 3D printing, is responsible for this enhancement. Compared with auxiliary heating and post thermal annealing treatment, the tensile property and cyclic fatigue behavior of CF/ABS specimen was equivalent. Notably, auxiliary heating is the “in-situ” annealing during the process of 3D printing, which can break through the existing dimension constraints of post thermal annealing treatment. Therefore, the approach broadens the design for CF/ABS composites through temperature-specific optimization and makes it possible to fabricate huge-size FDM parts.

Fracture Surface of 3D Printed Honeycomb Structures at Low Temperature Environments.

In this paper, surface characteristics of 3D printed structures fractured at low temperature environments are analyzed. The samples are fabricated by using ABS (acrylonitrile butadiene styrene copolymer) material, and the structures are constructed by the well-known honeycomb models using a FDM-Type 3D printer. To analyze the fracture surface of the samples constructed uniquely by using the 3D printer, the bending loads are applied to the samples at 30, -10 and -50 °C, respectively. The characteristics of the fracture surfaces of the 3D samples are also observed by the FE-SEM (field emission scanning electron microscope) equipment. From this experiment, it is evaluated that the fractured surface of the 3D sample is very rough at 30 °C, while it is smooth at a relatively low temperature. Also, several unique features of the fracture surface of a 3D printed sample structured by honeycomb models are also examined.

Properties of thin coatings deposited by physical vapour deposition on safety helmets

This article presents research on a new solution for industrial helmets improving mechanical and physical properties (temperature resistance and reflection of infrared radiation). The application of known technology in a new personal protective equipment area has been described in order to increase their level of safety and comfort of use. In this work we have studied the effect of a selected magnetron sputtering coating method onto polymer substrates, such as acrylonitrile–butadiene–styrene copolymer, polycarbonate, polyethylene, high-density polyethylene, polyamide, glass and silicon. Coatings made of copper, aluminium, TiN and TiAl were used. This work aims at identifying the best substrates for coating deposition improving the quality of protective helmets. On the basis of the obtained results, it can be stated that the TiN coating provides the best protection from infrared radiation and the best scratch resistance.

Thermal analysis and hazards evaluation for HTP-65W through calorimetric technologies and simulation

Di-tert-butyl peroxy-hexahydro terephthalate (HTP-65W), a newly developed organic peroxide, has been used in manufacturing acrylonitrile–butadiene–styrene copolymer and as an initiator in the polymerization. However, few studies focus on the thermal hazards of HTP-65W. The purpose of this study was to investigate the thermal decomposition phenomenon of HTP-65W under different conditions via calorimetric technologies and simulation. According to simultaneous thermogravimetric analyzer curves, two mass loss stages were detected at about 79 °C and around 64–72% mass loss happened in the first stage. Furthermore, the real view system was used to observe the apparent physical phenomenon like color and state change in HTP-65W during the reaction. Utilizing accelerating rate calorimeter and adiabatic kinetic method, the exothermic phenomena occurred at around 75 °C. The apparent activation energy (Ea) and rate constant of reaction under adiabatic conditions were 172.0 kJ mol−1 and 4.0 × 1025 mol L−1 s−1. Through differential scanning calorimetry and kinetics simulation, an exothermic peak appeared between 87 and 168 °C caused by the thermal decomposition of HTP-65W, and the Ea calculated using Flynn–Wall–Ozawa and Friedman methods were 143.4 and 128.4 kJ mol−1, respectively. To prevent thermal loss prevention accidents, time to maximum rate under adiabatic condition was obtained as 24 h under 63.9 °C and self-accelerating decomposition temperature was 61 °C for 50 kg package size of HTP-65W. Results of this study can support to prevent the potential thermal hazards of HTP-65W happened during storage, transportation, and manufacturing process.

Flotation separation of polyethylene terephthalate from waste packaging plastics through ethylene glycol pretreatment assisted by sonication

The recycling of packaging plastics is hindered by the various plastic mixtures and their similar surface properties. Plastic separation is a key step to improve recycling efficiency of waste plastics. We proposed a simple and efficient protocol to separate polyethylene terephthalate (PET) from polycarbonate (PC), acrylonitrile–butadienestyrene copolymer (ABS), and polyvinyl chloride (PVC) by converting PET surface from hydrophobicity to hydrophilicity. PET surface was modified by potassiumhydroxide (KOH)and ethylene glycol ((CH2OH)2) with the aid of sonication. Contact angle, Fourier transform infrared spectroscopy (FTIR), and X-ray photoelectron spectroscopy (XPS) were used to research the reactions on PET surface. It can be confirmed that the reaction of base-catalyzed transesterification occurs, leading to a hydrophilic PET plastic. We investigated the effects of ultrasonic power, ultrasonic time, (CH2OH)2 dosage, KOH dosage, flotation time, and frother concentration on the flotation separation. The flotation recovery and purity of PET are 98.8% and 100%, respectively when (CH2OH)2 dosage is 10 mL, KOH dosage is 2 g, ultrasonic time is 5 min, ultrasonic intensity is 160 W, flotation time is 4 min, and frother concentration is 52.7 mg/L. This study provided a novel surface modification with reliable mechanisms for the flotation of PET from plastic mixtures.

Development of a noble aluminum‐pigmented metallic polymer: Recommendations for visible flow and weld line mitigation

AbstractWe investigated the appearance of flow and weld lines when metallic pigments are used in polymer blends and how such lines can be eliminated by improving the pigment particle shape and optimizing pigment loading. Acrylonitrile butadiene styrene copolymer and two types of aluminum flakes, lamellar and three‐dimensional (3D), were blended in a twin‐screw extruder with a screw diameter of 25 mm. The temperatures from the hopper to the nozzle were 140, 180, 220, 220, 220, 220, and 220°C. Weld and flow lines were observed using field‐emission scanning electron microscopy and energy dispersive X‐ray spectroscopy of specially manufactured injection specimens. In the flow line region, traditional lamellar flakes were randomly oriented, while 3D flakes exhibited a distinct and stable orientation. Based on these observations, flow and weld lines in a finished metal/polymer blend can be minimized by using 3D metal particles in place of lamellar flakes. We also investigated the effects of aluminum flake loading on weld and flow line visibility. At low loading, weld lines were clearly visible due to the lack of pigmentation in the front of the polymer flow. Conversely, high loading resulted in relatively high concentrations of pigment near the weld line area, reducing weld line visibility. These findings suggest that there is an optimum metal loading level where the visibility of flow and weld lines is minimized.

Strong Biomimetic Immobilization of Pt-Particle Catalyst on ABS Substrate Using Polydopamine and Its Application for Contact-Lens Cleaning with H2O2.

Polydopamine (PDA)—a known adhesive coating material—was used herein to strongly immobilize a Pt-particle catalyst on an acrylonitrile–butadiene–styrene copolymer (ABS) substrate. Previous studies have shown that the poor adhesion between Pt particles and ABS surfaces is a considerable problem, leading to low catalytic durability for H2O2 decomposition during contact-lens cleaning. First, the ABS substrate was coated with PDA, and the PDA film was evaluated by X-ray photoelectron spectroscopy. Second, Pt particles were immobilized on the PDA-coated ABS substrate (ABS-PDA) using the electron-beam irradiation reduction method. The Pt particles immobilized on ABS-PDA (Pt/ABS-PDA) were observed using a scanning electron microscope. The Pt-loading weight was measured by inductively coupled plasma atomic emission spectroscopy. Third, the catalytic activity of the Pt/ABS-PDA was evaluated as the residual H2O2 concentration after immersing it in a 35,000-ppm H2O2 solution (the target value was less than 100 ppm). The catalytic durability was evaluated as the residual H2O2 concentration after repeated use. The PDA coating drastically improved both the catalytic activity and durability because of the high Pt-loading weight and strong adhesion among Pt particles, PDA, and the ABS substrate. Plasma treatment prior to PDA coating further improved the catalytic durability.
