Effects on the electro-mechanical properties of aniline-doped polyester fibric

Abstract

The effects of Electro-mechanical properties of doped polyester fabric with aniline were investigated. The effects of various concentrations on the electrical as well as mechanical were examined and the percolation threshold was established. Chemical polymerization of aniline on Polyester in hydrochloric acid using potassium dichromate as oxidant was carried out. Polyester based conductive polymer composites were prepared by means of melt mixing with a twin screw. The samples were investigated for electrocoductivity and mechanical properties. The results obtained shows polyester fabric became electrically conductive at a percolation threshold between 1-2.5% concentrations and also the electrical conductivity increased with the concentration, up to 5.0x10-3 S/m at 5 % concentration. The tensile characteristics such as average breaking force, work-to-rupture, and % elongation, of the fabric were all improved. Also Scanning Electron Microscope (SEM) analysis of the samples was studied.
