Vapor phase polymerization of PEDOT on silicone rubber as flexible large strain sensor

  • Received: 24 August 2015 Accepted: 27 October 2015 Published: 31 October 2015
  • This paper presents a flexible large strain sensor made from ethylenedioxythiophene deposited on silicone rubber (Ecoflex® 00-30) via vacuum assisted vapor phase polymerization (VPP) process. EDOT was used due to its stability when exposed to the atmosphere. VPP is a very simple process requiring only a vacuum bell jar and a vacuum pump. Ferrite chloride (FeCl3) dissolved in tethrahydrofuran was used as the oxidant to make the resulting poly(3,4-ethylenedioxythiophene) (PEDOT) conductive. THF was used because it swells Ecoflex® for better infusion of oxidant and PEDOT adherence. The sensor performs reliably up to 80% strain with a gauge factor of ~2.4 and small hysteresis.
