Production of Value-Added Composites from Aluminum–Plastic
Aluminum–plastic multilayer films have been widely used in the packaging industry, but the recycling of such a material is a great challenging task. Herein, we reported a facile route to produce value-added composites with high thermal conductivity and high electrical insulation from aluminum–plastic package waste (APPW) for the first time. Although a much milder solid-state process than ball milling, SSSP is accompanied by sufficient shear stresses and compressional forces to cause repeated fragmentation and fusion of material; conditions are tuned by feed rate, screw speed, screw design, and temperature [56]. In addition to being solventless, SSSP is industrially scalable.Maleic anhydride functionalization of polypropylene with suppressed
