膜構造材料
Document Type and Number:
Japanese Patent JP3858176
Kind Code:
B2
Abstract:
A material for a film structure having a base fabric comprising a glass fiber as a primary material and, formed on the surface of the fabric, a fluororesin surface layer, characterized in that the fluororesin surface layer contains a colorless and transparent or a white photocatalyst powder being carried thereon in an exposed state. The photocatalyst is preferably an anatase-type titanium dioxide having a high photocatalyst activity, and the fluororesin is preferably a tetrafluoroethylene-hexafluoropropylene copolymer. The material for a film structure is capable of decomposing and removing a stain comprising an organic material sticked thereto through decomposition or hydrophilization by photooxidation and thus exhibits high antifouling property for a long period of time. Further, the material allows the suppression of static electricity generated and accumulated by the friction or abrasion due to the fluttering by wind or the like or the contact with another material, which leads to the reduction of the sticking of dust, fine sands, or the like causing a stain.
