Abstract

Moth bean starch was modified through microwave assisted synthesis using a very low concentration of free radical initiator. Grafted copolymer was characterized by Fourier transform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM), X-ray diffraction (XRD), and thermogravimetric analysis (TGA). Swelling study was also performed at various temperatures to access its suitability in diverse industrial application. Starch-grafted-acrylamide could be efficiently synthesized using a small concentration of ceric ammonium nitrate (CAN) in aqueous medium under microwave irradiation. The FT-IR spectral analysis confirms group attachment on starch backbone. XRD and SEM studies confirmed more crystalline structure, while TGA confirmed high thermal stability as compared to native starch. Starchg acrylamide was successfully grafted and this novel biomaterial could be used in various industrial applications like food, textile paper, petroleum and pharmaceutical.
