The influence of the type and concentration of oxidants on the dielectric constant of the polypyrrole-coated plain woven cotton fabric

Abstract

The influences of the type and concentration of the oxidant on the real and imaginary parts of the dielectric constant, the loss tangent, and the surface resistance of the polypyrrole-coated plain woven cotton fabric were investigated. Subsequently, exterior morphologies were analyzed. The results showed that the type and concentration of the oxidant had a major influence on the real and imaginary parts of the dielectric constant, the loss tangent, and the surface resistance of the polypyrrole-coated plain woven cotton fabric. The composites showed good performance in terms of the dielectric properties, and conductivity. The ability of coupling is relatively good in the group whose molar ratio of the dosage of oxidant and pyrrole is 2:3. The dosage of oxidant has a major influence on the resistance of the polypyrrole-coated plain woven cotton fabric. When the initial molar ratio of the iron (III) chloride and pyrrole is 3:2, the value of the surface resistance is at its smallest, and the electrical conductivity is at its best.
