Title:
ELECTRIFICATION PREVENTING METHOD, AND ELECTRIFICATION PREVENTIVE COMPOSITE MATERIAL
Document Type and Number:
Japanese Patent JPH09232096
Kind Code:
A
Abstract:
To prevent the static electrification of a surface, by radiating light to an optical conductor photocatalyst containing layer, for coating electrically insulating base material, to optically excite a photocatalyst, and the surface of the layer is made hydrophilic, to adsorb humidity in air to the surface.
An electrically insulating base material (a ceramic and a tile, etc.) is coated by a layer, composed of a cilicone composition containing a semiconductive photocatalyst (TiO2 is preferableast), so that the coat thickness can be 0.2μm or less. Light such as the sunlight, etc., is radiated to the base material, to optically excite the photocatalyst; and the surface of the layer is made hydrophilic to about 10° or less calculated in terms of a contact angle with water, to adsorb a moisture content in air into the layer surface. This can prevent the static electrification on the base material surface.
