Semi conducting polyaniline (PANI)/MCM-41 composites has been synthesized by an in situ polymerization technique. The polyaniline-MCM-41 composite was made using aniline adsorbed on MCM-41, and then polymerized using ammonium peroxydisulfate, after the formation of aniline hydrochloride cation by the aggregacion of HCl. The Uv-Vis spectrum of PANI with characteristic maxima (ëmax) at 425, 575 and 725 nm was found. The FTIR analysis of the PANI-MCM-41 show the bands attributed at N-H stretching at 3400-3100 and the bands at 1580-1590 cm-1 and 1500+/-10 cm-1 attributed to the quinone and aromatic ring deformations.
