Polystyrene Composites Prepared with Polystyrene Grafted-fibers of Sugarcane Bagasse as Reinforcing Material
Keywords:Recycling, polystyrene, natural fibers, sugarcane bagasse, composites.
Bagasse Fibers of sugarcane were modified with dichloromethylvinylsilane and consecutively grafted with polystyrene. For unmodified fibers, TGA showed two maximum decomposition peaks at 320°C and at 370°C. For silanized fibers, the most stable stage was shifted to a higher temperature of 470°C and to 510°C for silanized and polystyrene grafted fibers. Young moduli of composites increased from 1.9 GPa for non-treated fibers to 3.3 GPa for silanized and polystyrene grafted fibers.
