Novel High Gamma Radiation Shielding Nanocomposites of Polyvinyl Pyrrolidone-Carboxymethyl Cellulose Blend Dispersed with ZnO Nanoparticles for Radiation Sensor

摘要

In this paper, design new types of shielding materials nanocomposites for gamma radiation shielding. Preparation of polyvinyl pyrrolidone (PVP)-carboxymethyl cellulose (CMC) blend and zinc oxide nanoparticles nanocomposites has been investigated with different concentrations of polymer bend and metal oxide nanoparticles. The FTIR analysis, electrical conductivity and optical properties have been studied for gamma ray shielding applications. The results showed that the electrical conductivity increases with increasing of zinc oxide nanoparticles concentration. The absorbance increases and energy band gap decreases with increase the ZnO nanoparticles concentration. Applications results of nanocomposites showed the (PVP-CMC-ZnO) nanocomposites have high linear attenuation coefficients for Co-60 and Cs-137 gamma ray sources.
