Silica mesoporous materials were obtained following the sol–gel method and post-synthesis alumination. These methods were effective for the synthesis of SBA-3 and SBA-16, showing XRD patterns and other characteristics in agreement with the literature. Aniline-saturated hosts were prepared by adsorption of aniline (exposed to the equilibrium vapors from liquid aniline) into the mesoporous materials. Polyaniline/Na-AlSBA-3 (PANI-3) and polyaniline/ Na-AlSBA-16 (PANI-16) composites have been synthesized by an in situ polymerization of aniline- saturated hosts. TG, FTIR, XRD, SEM and TEM were used to characterize the resulting composites. These studies show that PANI is generated inside the channel of the hosts. PANI-16 has an amount of emeraldine salt higher than PANI-3 composite. The electrical conductivity measurements confirmed that PANI and mesoporous materials were true hybrid nanocomposites. The conductive properties of these composites were compared with those of other compositespdfengopenAccesshttp://creativecommons.org/licenses/by-nc-nd/4.0/Attribution-NonCommercial-NoDerivatives 4.0 InternacionalCompositesNanostructuresPolymersInfrared spectroscopyX-ray diffractioninfo:eu-repo/semantics/articleBeltramone, Andrea Raquel_X_Atribución (Attribution): En cualquier explotación de la obra autorizada por la licencia será necesario reconocer la autoría (obligatoria en todos los casos). _X_No comercial (Non Commercial): La explotación de la obra queda limitada a usos no comerciales. _X_Sin obras derivadas (No Derivate Works): La autorización para explotar la obra no incluye la posibilidad de crear una obra derivada (traducciones, adaptaciones, etc.). _X_Compartir igual (Share Alike): La explotación autorizada incluye la creación de obras derivadas siempre que se mantenga la misma licencia al ser divulgadas.-
