An Investigation of Fabrication Cellulose Fibers-Polymer Using Recycled Polystyrene and Waste Newspaper

An investigation of fabricating cellolusic fibers-polymer composite using recycled polystyrene and waste newspaper was conducted. Today, recycling of polymers is very important because of undegradability of polymers and economical considerations. In this study, samples were prepared from paper fibers and polystyrene, where recycled newspaper fiber were mixed with recycled polystyrene at different levels (i.e., 10, 20 and 30% by wt.). Maleic anhydrided (MA) was added as coupling agent at 0, 1, 2 and 3% by wt. Mechanical properties of the composite were studied. It was found that adding MA increased the tensile strength. With increasing paper fibers, elastin modulus increased. The highest notch impact strength was obtained in sample which contained 20% paper fibers and 2% MA.
