Graft Copolymerization of Acrylonitrile Onto Wheat Straw Cellulose By Silane Coupling Agent

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#
