Nanostructured silicate SBA-15 and aluminosilicate AlSBA-15 were synthesized in order to prepare polyindole composites. The Silica mesoporous materials were prepared by sol?gel method and the alumination by post-synthesis technique, and analyzed by different methods (XRD, BET, TEM, and FTIR). From the structural point of view, the conductive polymers are polymeric with double bonds conjugated in their main chain, being polyheterocycles one of the groups most characteristic of this type of materials. In this work show the synthesis and characterization of new composites using nanowires of conducting polymers included in nanostructured hosts, based polyindole obtained by in-situ oxidative polymerization of corresponding pre-adsorbed monomers onto de hosts, producing hybrid composites with interesting conducting properties. Polyindole/host composites were prepared by an oxidative in situ polymerization of preadsorbed indole, employing Cl3Fe as oxidant. TG, FTIR, BET, XRD, SEM and TEM were used to characterize the resulting composites. These studies show that after polymerization, the porous structures of the materials are preserved and the Polyindole is found within the porous channels. The composites have an electrical conductivity range between higher than the pure polyindole chemically synthesized, close to the electrical conductivity of pure polymer electrochemically synthesized, and lower than the pure polymer chemically synthesized, in order of 10-8 S/cm.
