Abstract:

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 -0.42—0 V to 0—1.0 V vs. SCE.

Key words: Poly(3,4-ethylenedioxythiophene), Conductive textile, In-situ polymerization, Electrochromic behavior
