Synthesis, characterization and electrical insulation of polyester plasma sprayed by (CaO3Si/CuO) nanoparticles

Abstract Textile fabrics possess multitude applications and a wide variety of highly technical uses. Microfiber is one of the most popular synthetic fibers. Its popularity is a result of special properties such as good resiliency, heat resistance, light weight, water proof and durability. In the present work, two woven fabrics were synthesized from polyester microfiber and then coated by calcium silicate/copper oxide-nanoparticles, (CaO3Si/CuO)-NPs, using low temperature plasma (dielectric barrier discharge) technique. The coated textiles were investigated by Scanning Electron Microscopy (SEM) and Energy Dispersive X-ray (EDX). A broadband dielectric spectroscopy (BDS) was employed to study the treatment conditions on the electrical and dielectric properties over a wide range of frequencies. The results showed that, the resistivity of the textile samples was remarkably enhanced upon coating with the (CaO3Si/CuO)-NPs) accompanied by a reduction of the static charges accumulated on the surface. These results made the plasma sprayed coated textiles promising for electrical applications like cables isolation as well as packing and packaging.
