Patent ID: 8420040

Claim:
An organic-inorganic composite, comprising: a non-swelling layered silicate comprising mica and having K ions between layers of the non-swelling layered silicate and an average particle size of primary particles of 2 μm to 500 μm; and a positively charged organic compound, wherein the positively charged organic compound is directly intercalated into the non-swelling layered silicate, the layered silicate is represented as the following formula: [(K a M 0.1-b )(X c Y d )(Si 4-e Al e )O 10 (OH f F 2-f )] wherein 0.6≦a≦1.0, 0≦b≦0.1, 1.0≦c≦3, 0≦d≦2, 2≦c+d≦3, 0≦e≦4, 0≦f≦2; M is a cation other than K which is between layers and at least one of Li, Na, Rb, Cs, NH 4 , Be, Mg, Ca, Sr, Ba, Mn, Fe, Ni, Cu, Zn and Al; X and Y are metals enclosed in an octahedral formed in a 2:1 typed sheet; X is at least one of Mg, Fe, Mn, Ni, Zn and Li; and Y is at least one of Al, Fe, Mn and Cr, and the K ion is ion-exchanged with the positively charged organic compound, and 0.6 to 5 equivalents of the positively charged organic compound to a cation exchange volume of the layered silicate are contained in the organic-inorganic composite.
