Thin film formation of PEDOT conductive polymer and PVDF piezoelectric polymer by dip-coating method assuming application to flexible power generation element

摘要

Poly(3,4-ethylenedioxythiophene) (PEDOT) conductive polymer and polyvinylidene difluoride (PVDF) piezoelectric polymer thin films were formed by dip-coating method. The relationship between drawing speed and film thickness was experimentally investigated. Dip-coated PEDOT and PVDF thin films were characterized and confirmed that both had surely worked as electrode and piezoelectric film of a flexible power generation element, respectively. Using dip-coating method, these thin films were successfully formed on 3D surface of a bellows shaped spring made of silicone rubber.
