摘要:
Disclosed are antifouling material possessing excellent surface antifouling properties, particularly excellent antifouling activity against greasy stains and soils, a process for producing the same, and a coating composition and an apparatus for the antifouling material. The antifouling material comprises: a substrate; and an inorganic layer consisting essentially of an amorphous metal oxide, the inorganic layer containing an alkali metal and non-bridging oxygen in an amount effective in removing contaminants, derived from an exhaust gas, adhered on the surface of the inorganic layer by cleaning using running water alone to restore the diffuse reflectance of the surface of the inorganic layer to not less than 75% of the initial diffuse reflectance, the inorganic layer constituting the outermost fixed layer of the antifouling material.

Disclosed is a method and an apparatus are provided which can efficiently produce a functional material having a satisfactory level of photocatalytic activity. A photocatalyst coating composition comprising a photocatalytic metal oxide and/or a precursor of the photocatalytic metal oxide is coated on the surface of a substrate. The surface of the coated substrate is rapidly heated to fix the photocatalytic metal oxide onto the surface of the substrate. This rapid heating can realize the production of a functional material having a satisfactory level of photocatalytic activity in an efficient manner. The apparatus, which can continuously carry out the rapid heating immediately after the production of the substrate, can produce the functional material having photocatalytic activity in an efficient manner.
摘要:
Multi-functional materials which have a photocatalytic layer with a photocatalytic function disposed on the surface of a base through a binder layer 6 interposed therebetween. Photocatalytic particles of the photocatalytic layer are joined together by a surface energy or solid-state sintering. The photocatalytic layer may have a structure in which fine particles fill interstices defined between photocatalytic particles or a structure in which no fine particles fill interstices defined between photocatalytic particles. A metal such as Ag, Pt, or the like may be fixed or not fixed to surfaces of the photocatalytic particles.

Multi-functional materials are classified into those which have a photocatalytic layer 2 with a photocatalytic function directly disposed on the surface of a base 1 and those which have a photocatalytic layer 2 with a photocatalytic function disposed on the surface of a base 1 through a binder layer 6 interposed therebetween. Photocatalytic particles of the photocatalytic layer 2 are joined together by a surface energy or solid-state sintering. The photocatalytic layer 2 may have a structure in which fine particles fill interstices defined between photocatalytic particles or a structure in which no fine particles fill interstices defined between photocatalytic particles. A metal such as Ag, Pt, or the like may be fixed or not fixed to surfaces of the photocatalytic particles.

A lower layer of the photocatalytic layer is embedded in the binder layer such that an intermediate layer is formed between the binder layer and the photocatalytic layer, the intermediate layer including components of the binder and photocatalytic layers in varying concentrations therethrough.
