Investigations on polyaniline-TiO2 nano-composite Langmuir Blodgett thin films

Polyaniline-TiO₂ nano-composite materials were prepared by in-situ polymerization of aniline with TiO₂ [1]. The incorporation of the titania in the composites was endorsed by Fourier Transform Infrared Spectroscopy (FTIR) studies. Electron Absorption Spectroscopy for PANI-TiO₂ composites and its LB films revealed that nanoparticles improve absorption due to increase in surface area as compared to bulk. The polyaniline-TiO₂ nano-composite Langmuir Blodgett film deposited on the smooth silicon substrate were characterized by Atomic Force Microscopy (AFM).
