Abstract
An improved extrudable solution such as a cellulose acetate/acetone spinning solution is provided containing cellulose ester, solvent, metal oxide precursor, acid, and water. The solution is extruded such as by spinning and produces a shaped article such as a cellulose acetate fiber containing metal oxide interpenetrating networks.
