Electrostatic Discharge Properties of Modified Poly(3,4-ethylenedioxythiophene) /Poly(4-styrenesulfonate) Coated Hydrophobic Fabric

Abstract

The conductivity of poly(3,4-ethylenedioxythiophene)(PEDOT) doped with poly(4-styrenesulfonate) (PSS) containing various organic solvents was measured. The solvents used were isopropanol (IPA), dimethyl sulfoxide (DMSO), N-methyl-2-pyrrolidone (NMP), N,N-dimethyl acetamide(DMAC).It was found that an addition of organic solvent lowered the sheet resistance by two or three orders of magnitude. Conducting PEDOT/PSS solution mix with polymethyl methacrylate(PMMA) resin to coat hydrophobic fabrics, which can be used for the dissipation of electrostatic charge. We design different screen patterns (square, round, cross, triangle) and utilize it coating PET fabrics, witch are subjected to electric conductivity and electrostatic discharge. Attenuation of the electrostatic discharge (ESD) for various pattern shape be described. We adopt percolation theory to analyze different shape conductive films relate with electric conductivity, in order to find out the best pattern shape and prescription.
