Synthesis and characterization of polyvinyl butyral–Al(NO3)3 composite sol used for alumina based fibers

The polyvinyl butyral–Al(NO 3 ) 3 composite sol used for alumina based fibers was synthesized by the sol–gel process in an aqueous solution using the polyvinyl butyral (PVB) and Al(NO 3 ) 3 · 9H 2 O (AN). The alumina fibers with smooth surface and uniform diameter were prepared. PVB, AN, PVB–AN com...
