Preparation and Characterization of MMT Doped PVA/SA Polymer Composites
ABSTRACT
Blends of PVA/SA polymer doped with Montmorillonite were prepared by solution casting technique. Doping of nanoparticles to the polymer matrix does affect the structural and conducting properties. To analyze such changes, these films were subjected to X-ray diffraction, FT-IR spectroscopy, UV-visible absorbance and impedance analysis. Microstructural parameters were computed using in-house program employing X-ray data. Electrical conductivity of these polymer composites was derived using obtained impedance values to understand the conducting property. The results thus obtained are reported in this work.
