Resumo

Composites of polyaniline (PANI) with MCM-41 and SBA-15 ordered mesoporous silicas were prepared by liquid and vapor monomer adsorption methods. Both methods resulted in polymer encapsulation inside the mesopores, but a higher amount was obtained using the vapor adsorption method. Composites presented a semiconductor behavior and the charge transport mechanism was consistent with a hopping process between localized states. Based on the results of one-dimensional variable range hopping (1D-VRH) conduction parameters, the SBA-15 with polyaniline incorporated by vapor adsorption was the more conductive and ordered material.
