10. A method of preparing inorganic-organic nanocomposite comprising the steps of:
-
a) reacting an aminosilane possessing at least one hydrolyzable alkoxy group with water, optionally, in the presence of catalyst, to provide amine-terminated organopolysiloxane;
b) quaternizing the amine-terminated organopolysiloxane to provide a quarternized organopolysiloxane; and
,c) combining the quaternized organopolysiloxane with layered inorganic nanoparticulate possessing exchangeable cation to provide inorganic-organic nanocomposite. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 21, 22, 23)
