Abstract

A method of forming nano composites within a polymer structure comprises exposing a wettable polymer having ion-exchangeable groups pendant therefrom to an aqueous solution of a soluble salt containing metal ions, the metal ions replacing, by ion exchange, the pendant groups on the polymer. After ion exchange the polymer is exposed to a reducing agent forming metal oxides trapped within the polymer structure.
