1. An inorganic-organic nanocomposite comprising at least one inorganic component which is a layered inorganic nanoparticulate and at least one organic component which is a quaternary ammonium-containing organopolysiloxane, wherein the quaternary ammonium groups are positioned at the terminal ends of the organopolysiloxane and along the siloxane backbone, and wherein the quaternary ammonium organopolysiloxane is obtained by hydrosilating a polydiorganosiloxane possessing Si-H bonds with allylamine in the presence of hydrosilation catalyst to provide amine-containing organopolysiloxane and thereafter quaternizing the amine-containing organopolysiloxane to obtain the quaternary ammonium organopolysiloxane.
