Flexible and lead-free polymer composites for X-ray shielding: comparison of polyvinyl chloride matrix filled with nanoparticles of tungsten oxides.

Polymer nanocomposites have been investigated as lightweight and suitable alternatives to lead-based clothing. The present study aims to fabricate flexible, lead-free, X-ray-shielding composites using a polyvinyl chloride (PVC) matrix and different nanostructures. Four different nanostructures containing impure tungsten oxide, tungsten oxide (WO), barium tungstate (BaWO), and bismuth tungstate (BiWO) were synthesized through various methods.

Coating of polyester fabrics with micro-particles of BiO and BaO for ionization ray shielding.

The aim of the present study is to fabricate an economical, environmentally friendly, easily workable, light-weight and comfortable textile-based radiation shield. At first, polyester fabrics were coated with PVA resin that contained bismuth micro-particles (BiO) and barium oxide (BaO) powder in two different weight ratios. Then, the fabric samples were exposed to a source of Ra.
