Electrical and physicochemical properties of PEDOT-based organic-inorganic hybrid conductive thin films
Conductive polymer coating precursors were prepared using poly (3,4-ethylenedioxy thiophene)(PEDOT) and three kinds of silane precursors (Q type, T type, and bridged T type) through an in-situ organic/inorganic hybrid sol-gel process. The spin-coated precursor films on a PET (polyethyleneterephthalate) substrate exhibited fairly good surface resistance (～104Ω/□), transparency (～ 80 ％) and pencil hardness (2～4H). The solvent resistance of the film using 2, 5-bis (triethoxysilyi)-3, 4-ethylenedioxythiophene (BTES-EDOT) was excellent as compared with the films that used silane precursors due to a high degree of BTES-EDOT crosslinking in the hybrid film. Moreover, EDOT moiety in the BTES-EDOT molecule may contribute to homogeneous dispersion of the PEDOT in the organic-inorganic hybrid film.
