Abstract Biodegradable polymers, including polybutylene adipate-co-terephthalate (PBAT), can replace traditional plastics to effectively target microplastic pollution; however, their high cost limits their application. In this study, vinyltrimethoxysilane (VTMS)-grafted lignin (VL) was prepared and incorporated into PBAT to reduce its cost and improve its mechanical properties while maintaining its biodegradability. Results show that the tensile strength, Young's modulus, and biodegradation effi...

Abstract Improving complexation at the interfaces and regulating the crystal transformation behaviors of polyamide 6 (PA6) composites with high mechanical and thermal properties are essential for the industrial applications of PA6. In this work, the effects of adding p (N-(4-F-phenylmaleimide)-alt-styrene) (PFS) on the crystal transformation, thermostability, thermal conductivity, and mechanical properties of PA6 were investigated and discussed systematically. The resu---lts from heat deflection...

Abstract In order to expand its application range in electronics and membrane industries, this paper aimed to develop polyamide 6 (PA6)/P (N-(4-carboxyphenyl) maleimide-alt-triallyl isocyanurate) (PCT) composites with heat-resisting, thermally conductive and anti-moisture, by employing PCT as a reactive reinforcement material and applying irradiation for solid-state interfacial reaction (SSIR) between PCT and PA6. According to the results, the SSIR occurred between PA6 and PCT. Compared with non...

To expand the use of polylactic acid (PLA) in high-temperature environments, crystallization morphology regulation was studied to enhance the heat resistance of PLA. PLA crystallinity was controlled using heat treatment and nucleating agent (zinc phenylphosphonate, brand TMC). The heat deflection temperatures of PLAs with same crystallinities considerably varied using different treatments. The crystallization morphology of PLA (4032D) and PLA/TMC composites was studied using X-ray diffraction (X...

Poly(N-(3-carboxyphenyl)maleimide-alt-styrene) with superior heat-resistance was synthesized by free radical copolymerization and its structure was confirmed by FTIR and NMR spectroscopy. To show the advantages in heat-resistance of the synthesized copolymers, the thermal properties of poly(N-phenylmaleimide-alt-styrene) and poly(N-phenylmaleimide-alt-maleic anhydride) with similar structures were determined. DSC/TG analysis showed that the synthesized copolymer exhibited the better thermal prop...

P(N-phenylmaleimide-alt-styrene) (P(NPMI-alt-St)) and P(N-(4-carboxyphenyl)maleimide-alt-styrene) (P(CPMI-alt-St)) were designed and synthesized via free radical copolymerization. Fourier transform infrared spectroscopy (FT-IR), nuclear magnetic resonance spectroscopy (1H NMR and 13C NMR), gel permeation chromatography (GPC), and differential scanning calorimetry (DSC) were used to confirm the structure of P(NPMI-alt-St) and P(CPMI-alt-St). Next, the effect of P(CPMI-alt-St) on the heat deflecti...
