SYNTHESIS AND CHARACTERIZATION O POLYMERIC NANOCOMPOSITES

Abstract

Characterization of Polymeric Nanocomposites newlinedeals with the synthesis of various carboxymethyl guar gum based nanocomposites. newlineAn attempt has been taken to synthesize carboxymethyl guar gum/silver newlinenanocomposite for testing its ammonia sensing property and further antimicrobial newlineactivity against gram positive and gram negative bacterial. In the next attempt newlinecarboxymethyl guar gum nanoparticles have been synthesized by nanoprecipitation newlinemethod and further these nanoparticles were used as a stabilizer in newlinePolyaniline/CMGG nanocomposite. The aim was to improve the processing problem newlineof polyaniline. At the last attempt a biodegradable, conductive, flexible newlinepolyaniline/CMGG film has been prepared. Some of the expecting applications are as newlinefollowing. newlinea) To develop a liquid ammonia optical sensor by using carboxymethyl guar newlinegum/silver nanocomposite. newlineb) To synthesize an antimicrobial film for medical applications. newlineviii newlinec) To synthesize carboxymethyl guar gum nanoparticles for using as stabilizer to newlineimprove the processing problem of conductive polymers and to be used in newlineconductive nanopaint. newlined) To develop conductive, flexible, water insoluble film which might be used in tissue newlineengineering and drug delivery. newlineSo the entire work of the Ph.D. thesis has been divided into following five chapters.
