Abstract
Los materiales nanoestructurados Si-SBA-15 y AlSBA-15 se sintetizaron con el fin de preparar
composites de poliindol. Los materiales mesoporosos de sílice se prepararon mediante el método sol-
gel y la aluminación post-síntesis, y se analizaron mediante diferentes métodos (XRD, BET, TEM, y
FTIR). Los composites poliindol/hospedaje se prepararon mediante polimerización oxidativa in situ de
indol pre-adsorbido, empleando FeCl3 como oxidante. Para caracterizar los distintos composites se
utilizaron diferentes métodos TG, FTIR, BET, DRX, SEM y TEM. Estos estudios muestran que
después de la polimerización, las estructuras porosas de los materiales se conservan y el poliindol se
encuentra dentro de los canales porosos.
Los composites presentan una conductividad eléctrica en el rango de 8.7 10-4 y 1.4 10-8 S.cm-1
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). Polyindole/host composites were prepared by an oxidative in situ polymerization of pre- adsorbed indole, employing FeCl3 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 8.7 10-4 y 1.4 10-8 S.cm-1 .
