Transparent and Conductive PEDOT Films on PET Substrate Using an Epoxy Acrylate Binder


Article Preview

Flexible and thin conductive films of poly(3,4-ethylenedioxythiophene) (PEDOT) on PET substrate were obtained by an in- situ vapor-phase polymerization (VPP) method using ferric toluene sulfonate as an oxidant. The addition of epoxy acrylate resin used as a binder to provide adhesive strength between PEDOT and PET also afforded the possibility of the surface patterning through UV exposure. The electrical and optical properties of the conductive PEDOT films were characterized by UV-Vis spectroscopy and conductivity measurement. Surface resistance below 150./sq. was achieved for 100 nm thick films with UV-vis-spectrum transparency exceeding 80%. The combination of these properties makes the films highly suitable for numerous device applications.
