摘要

PROBLEM TO BE SOLVED: To provide a photocatalytic functional material controllable in wettability with water on the surface by heat-treatment.;SOLUTION: In this composite material, at least one kind or plural film constructing material are selected from the group consisting of at least one kind of semiconductor selected from titanium oxide, iron oxide, chromium oxide, tin oxide, zinc oxide, strontium titanate, tungsten oxide and copper oxide. The film structural material combinedly using at least one kind of metal is selected from at least one kind selected from the semiconductor group with at least one kind of metal selected from the group consisting of chromium, vanadium, niobium, iron, copper, cobalt, nickel and manganese.;COPYRIGHT: (C)2000,JPO
