Grafting of starch backbone done with monomers such as acrylic acid, methacrylate and acetonitrile through a free-radical mechanism in the presence of Lutensol XL-100 using an initiator ammonium per-sulphate with constant stirring and heating at temperature of 80ºC. Co-polymerization of acrylic acid, methacrylate and acetonitrile is the initial step followed by grafting. Nickel doped nanoparticles are attached on this grafted polymer to enhance the biodegradability property of starch. The property of this biodegradable mixture is studied by soil burial method. Study and analysis of these polymers is done with the help of FTIR, TGA and DSC and SEM. Results indicated that grafting is an efficient method to impart biodegradability to non-biodegradable polymers by the covalent attachment of monomers on starch backbone. Our research suggested that biodegradability of these grafted starch polymers enriched with nanoparticles increased and show resistance against Nano-composites with various strategies show resistance against microorganisms by oxidizing cell components or by making secondary products such heavy metal ions. These by-products ultimately led to the destruction of microbes so that can be used for packaging of food materials, in medical field to make clinical instruments for surgical purposes, for efficient delivery of drugs at targeted site and these biodegradable polymers is employed in agriculture field in the form of fibers and films due to their property of increased absorption of materials.
