Silica mesoporous materials were obtained following the sol–gel method and post-synthesis alumination. Pyrrole-saturated hosts were prepared by adsorption of pyrrole into the mesoporous materials. The adsorption/desorption of pyrrole was studied by FTIR. Molecules of pyrrole would be adsorbed through aromatic ring to the host. The polymerization technique was performed by oxidative way using different oxidizing agents, ammonium persulfate and ferric chloride, after pyrrole adsorption on both hosts. TG, FTIR, BET, XRD, SEM and TEM were used to characterize the resulting composites. These studies show that polypyrrole is generated inside the channel of the hosts; conductivity studies show that the composites exhibit conductivities at room temperature and in the range of 1 × 10—7 and 1 × 10—6 S cm—1 depending on the host and the oxidizing agents.pdfengopenAccesshttp://creativecommons.org/licenses/by-nc-nd/4.0/Attribution-NonCommercial-NoDerivatives 4.0 InternacionalcompositesnanostructuresPolymersinfraredinfrared 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.-
