After reaching maximum conductivity at 850 1C, the conductivity decreases with increase of the calcination temperature. The calcination holding...
Applicability of the sol-gel method to fabricate polymer-silica composites has been briefly reviewed. The sol-gel method has been applied for synthesis of nanosilica in mineral and naphthenic oils and also in latexes of diene copolymers. A new silane precursor of nanosilica was prepared by transest...
