ABSTRACT

Process of “grafting” is a very useful method for making branches or chemical modification in polymeric materials. Natural fiber reinforced thermoplastic composites grafting, in context of compatabilizer, can be done by two ways: one is pre-grafting (the polymer is first taken and grafted as compatabilizer) and another is ----in situ grafting. In ----in situ grafting process, polymer is grafted during the fabrication of composites/ blends. The later kind of compatibilization is also called reactive compatibilization. Polyolefins are commonly functionalized with maleic anhydride (MA) to enhance adhesion to polar materials and are used as a compatibilizer. The bamboo-fiber is often brittle compared to other natural fibers, because the fibers are covered with lignin and it undergoes degradation above 200°C (Seema and Kumar, 1994). Polyethylene (PE) and polypropylene (PP) are among the commonly used thermoplastics for the preparation of natural fiber reinforced composites due to their relatively low prices and good processability (Deshpande et al., 2000; Kim et al., 2006).
