Induction of Physico-Chemical and Thermal Resistance onSaccharum spontaneumL by Grafting Under Microwave Irradiation

Abstract

Grafting of methylmethacrylate (MMA) with acrylamide (AAm), acrylonitrile (AN), and acrylic acid (AA) in binary mixtures onto Saccharum spontaneum L (Ss), was carried out under microwave radiation (MW). The maximum graft yield (88.9%) was found with AAm binary mixture. Synthesized graft co-polymers were characterized with FT-IR, scanning electron microscopy (SEM), TGA=DTA=DTG, and X-ray diffraction (XRD) techniques. Thermal stability of Ss-g-poly(MMAþAAm) was found to be higher than that of S. spontaneum fiber and other graft co-polymers. Percentage crystallinity and crystallinity index decreased (85.32 À 77.11 and 0.82 À 0.70, respectively) after grafting but graft copolymers exhibited more moisture, chemical and thermal resistance.

Bioremediation of Natural Fiber by Graft Copolymerization

“…It is versatile chemical technique that incorporates the desired features in natural fiber without affecting their inherent traits. Various workers have carried out the graft copolymerization onto different cellulosic backbone using vinyl monomers through various chemical while using wide range of initiator, oxidizer, monomers, binary vinyl monomeric mixtures and radiation techniques and achieved fruitful results [13][14][15][16][17][18][19][20][21][22].…”
