Cellulosic fibers are finding their applications in many fields ranging from automotive to biomedical purposes. They also have wide applications as the reinforcement component in polymers to add the specific properties in the final product. Wheat straw (WS) cellulose is a low-cost lignocellulosic material. In this study, a grafted copolymer of poly(acrylonitrile-g-wheat straw) [poly(AN-g-WS)] was prepared by applying the alkaline surface modification method to obtain pure cellulose. A silane coupling agent (MPS) was used for the silanization of alkaline treated WS. Acrylonitrile monomer and AIBN initiator were used in the last step for graft copolymerization of poly(AN-g-WS). The poly(AN-g-WS) was functionalized, and characterized by Fourier transform infrared spectroscopy (FTIR), and X-ray diffraction spectroscopy (XRD). The results proved the potential of the prepared poly(AN-g-WS) for environmental applications.
