Abstract:
1. A method for producing an organic-inorganic composite material comprising: at least one organic polymer selected from the group consisting of polyamide, polyurethane, and polyurea, and an inorganic compound particle selected from the group consisting of metal oxides of groups 3 to 12 transition metal elements of the periodic table, metal oxides of main metal elements selected from the group consisting of 13 Al, 31 Ga, 32 Ge, 49 In, 50 Sn, 51 Sb, 82 Pb and 83 Bi of the periodic table, metal hydroxides of said transition and main metal elements, and metal carbonates of said transition and main metal elements, which is finely dispersed in the organic polymer matrix, wherein the inorganic compound particles have an average particle size which is not greater than 500 nm, and the content of the inorganic compound particles in the composite is from 20 to 80 weight % per 100 weight % of the composite,
