Abstract
Composites of gelatin and polythiophene sodium poly 2-(3-thienyl)-ethoxy-4-butylsulfonate (PTEBS) were prepared by solution casting. PTEBS content in the composites were in the range of (wt.%) 0.01-0.08%. The surface morphology of the composite films was investigated by means of a scanning electron microscope (SEM). The electrical conductivity of the composites has been found to show Ohmic behavior while the dielectric characteristics show normal characteristics. The light-harvesting ability of the composite films was investigated by UV-Visible spectroscopy. Throughout the investigation it has been observed that the electrical and dielectric properties, and light harvesting efficiency of the composite films improved significantly with the incorporation of PTEBS to the pure gelatin.
