Conductive poly（3,4-ethylenedioxythiophene） coated terylene textile represented by PEDOT/CTT was prepared via in-situ polymerization.It is found that the PEDOT nano-particles with diameter of 100 nm spread over the surface of terylene fibers resulting in a good conductivity of 2.67×10-2 S/cm,as measured by a four-probe method.Moreover,the PEDOT/CTT exhibits an electrochromic behavior,which takes a variation of color from pale blue to dark blue when the applied potential changed from-0.420 V to 01.0 V vs.SCE.
