Published: Feb. 13, 2025

Abstract To maximize the utilization of waste laser printed paper fiber (WLPF), WLPF was used as organic reinforcing phase, high‐density polyethylene (HDPE) matrix, vinyltrimethoxysilane (A171) and γ‐methacryloxytrimethoxysilane (KH570) were coupling agents to modify prepare WLPF/HDPE composites via a blending‐injection molding process. The weather resistance properties mechanisms systematically analyzed using scanning electron microscopy, Fourier‐transform infrared spectroscopy (FTIR), mechanical analysis, thermogravimetric differential calorimetry. results showed that KH570‐modified retained their excellent tensile flexural strength after 2000 h accelerated ultraviolet (UV) aging, strength, modulus 26.9, 41.0, 2744.4 MPa, respectively. thermal property analysis revealed stability decreased aging. Additionally, crystallization enthalpy, melting crystallinity increased. Highlights Waste fiber/high‐density (WLPF/HDPE) modified prepared by injection Ultraviolet aging investigated for first time. KH570 UV also investigated.

Abstract Based on the micro‐structure of wollastonite (WS) and bamboo flour (BF), a series PP/WS/BF ternary composite materials are prepared using blending, twin‐screw melt extrusion, injection molding processes. The experiment shows that formulation processing technology play significant impact structure, thermal, mechanical properties composites. BF has nucleation crystallization PP, while WS almost no effect PP. improves tensile strength enhances composites; bending flexural modulus rigidity Taking W‐B‐30‐1:3 sample as an example, its performance is highest at 23.33 MPa, well 26.23 904.67 respectively. combination leads to increase in storage modulus, decrease loss factor, glass transition temperature, bonding factor materials. This work can enrich scope PP materials, expected have potential applications fields automotive interior parts with lightweight. Highlights Heterogeneous among fillers Wollastonite more conducive improving thermal stability Adding effectively enhance properties. use increases interfacial compatibility performance.
