Abstract
A composite of sulfonic acid-functionalized mesoporous silica (MCM-41) with a polyaniline (PANI) conducting polymer was synthesized by in situ polymerization method. PANI/MCM-41 conducting polymer composites were characterized by Fourier Transform Infrared (FTIR), UV-Vis, thermogravimetric analysis (TGA), Four-point probe for conductivity measurement and 13C CP/MAS NMR. It was revealed that although conductivity of PANI was reduced after addition of MCM-41, its thermal stability of conductivity was significantly enhanced and demonstrated the desirability which efficacy of this polymer-mesoporous silica MCM-41 composite system in relatively high temperature applications.
