Studies on Polystyrene/Polymethyl methacrylate Thin-Films: Structural and optical Properties

Abstract

The thin film blends such as Polystyrene (PS) and Polymethyle Mythcrylate (PMMA) were prepared by dip coating technique. Pure and blended forms of thin films are to be characterized in the context of FTIR and XRD methods for micro structural analysis. AC conduction properties of polymers in the frequency range 10 kHz to 10 MHz at various temperatures (303–343 K) are reported and studies suggest that electron hopping is responsible for conduction. The activation energies associated with these thin films and optical properties are also studied.
