ENHANCING THE CONDUCTIVITY OF PANI THIN FILMS BY ADDITION OF CLAY

Electrical conductivity is the well known property of polyaniline (PANI) for which this material is used in wide range of applications. According to the way of its use various forms of PANI, from powder to thin films deposited on different substrates, are prepared. Glass represents one of the often used substrates, mainly due to its chemical stability and optical transparency. Therefore, PANI thin films deposited on glass allows us to utilize both electrical and optical properties. This work deals with the preparation and characterization of conductive and optically transparent PANI thin films followed by addition of montmorillonite (MMT) particles enhancing the conductivity along with maintaining the optical transparency, although in the narrower range of wavelengths.
