ABSTRACT
This chapter reports the comparative investigation of polyindole/poly(vinyl acetate) composites synthesized chemically using different oxidants. The nickel nitrate and cupric chloride were used as oxidants. The prepared samples were analyzed through Fourier-transform infrared spectroscopy, photoluminescence spectroscopy and ultraviolet-visible (UV-Vis) spectroscopy, field emission scanning electron microscopy (FE-SEM), and X-ray diffraction pattern (XRD). The optical bandgap energy values for composites were determined to be 4.26 and 4.79 eV for different oxidants. The determined optical bandgap energy has conventional value for the photovoltaic activities and also indicates that the composites have semiconducting properties. As-synthesized composites have application potential in optical devices and polymeric solar cells.
