Radiation Preparation and Characterization of Polymer Nano-composites using Gamma-Irradiation and Their Potential Applications

Abstract

This thesis includes the preparation of nanocomposite films based on natural biodegradable polymer which blended with synthetic one and incorporated with nanofiller by solvent casting method using gamma irradiation from 60Co as initiator. This work is divided into two main parts: 1-Preparation and characterization of Calcium alginate-Polyacrylamide/Titanium dioxide (CA-PAM/TiO2) nanocomposite films to be used in selective adsorption of Fe (III) from aqueous solution 2-Preparation and characterization of CA-PAM/TiO2/graphite nanocomposite films and their electrical conductivity studies. The main results obtained by this work can be summarized as follow: 1- Calcium alginate (CA) films prepared based on ionic crosslinking of Sodium alginate films prepared using gamma irradiation and effect of irradiation dose and Sodium alginate (SA) concentration on water solubility (%) of CA films showed that CA film prepared at 10 kGy and at SA concentration 4 (wt/v) has lowest solubility%
