Gamma attenuation through nano lead - nano copper PVC composites

Polymer composites of polyvinyl chloride, PVC, were loaded up with micro and nano PbO/CuO particles. The added percentage each by mass was 10 wt.%, 20 30 40 plus wt.% mixed composite (20 CuO + PbO). linear attenuation coefficients the investigated measured as a function gamma-ray energies going from 59.53 keV to 1408.01 utilizing standard radioactive point sources. To confirm validity these results for bulk (PVC PbO PVC CuO) calculated using XCOM software. in good agreement values obtained experimental work. By comparing different it found that those either or have higher than sizes same percentage. Also, samples highest even them PbO), especially energy region below 1 MeV, but greater energies, become very closed. investigation mechanical properties such due injection metals reveals tensile strength Young's modulus nanocomposite sheets notably increased increasing concentration nanoparticles. showed flexural strength, toughness, among all fabricated sheets.
