Poly (tetrafluoroethylene) thin films were deposited onto a perfluoroalkoxy vinyl ether (PFA) rubber substrate by a conventional vacuum evaporation apparatus. C-F2 unit can be observed in the FT-IR spectrum of the PTFE thin film deposited at room temperature. However, C-F and C-F3 units can be observed in the PTFE deposited with heating the substrate at 250°C in addition to the C-F2 unit. Surface free energies, friction coefficients and pull strength between the PTFE thin film and PFA rubber substrate increased with increase of the temperature of the substrate during the evaporation. These properties are predicted to be related with the thin film structures such as chemical bonding states and cross linking.
