Polyvinylalcohol-polythiophene (PVA-PTh) was synthesized on polyester (PET) substrate by vacuum evaporation and 0 ℃ low temperature vapor deposition to obtain a composite film of transparent conductive polymer with excellent properties. The effects of FeCl3 and PVA concentration ratio, reaction pressure, polymerization temperature and time on the transmittance and conductivity were studied. The optimum conditions were as follows: FeCl38.0wt%, PVA6.0wt%, pressure3.37 × 104Pa, temperature0 ℃, polymerization time10min in vapor deposition. The transmittance of the film at 550 nm is Tr ≧ 80%, the electrical conductivity ρ ≧ 0.2 s · cm-1, and the thickness of the film is about 1 μm.
