Abstract:
The present invention prevents a phenomenon in which a fluororesin film material including PTFE as a major material and having a photocatalyst layer on a surface of the PTFE gradually becomes dirty on the surface after the lapse of several years from initiation of the use.
The present invention forms a photocatalyst layer on the PTFE layer of a Type A film material, the photocatalyst layer comprising a photocatalyst and a fluororesin, the fluororesin comprising a combination of PTFE with FEP and/or PFA. It is preferable that the PTFE content be higher than the content of the FEP and/or PFA. It is preferable that the weight of the photocatalyst be 40% or less of the total weight of the photocatalyst and the fluororesin.
