Synthesis of ion-exchangeable layered polysiloxane by sol–gel reaction of aminoalkyltrialkoxysilane: a new preparation method for layered polysiloxane materials

Abstract

An ion-exchangeable layered polysiloxane containing alkylammonium groups was synthesized by sol–gel reaction of 3-aminopropyltrimethoxysilane (APTMOS) catalyzed by hydrochloric acid; the present reaction system provides a new method for the preparation of layered polysiloxane materials.
