Wide Band Gap Thermoset Renewable Polymer Graphite (TPG) Composites

Wide band gap thermoset renewable polymer graphite (TPG) composites thin films with different contents of graphite particles (ascending 5 wt.%) were prepared by slip casting method. Functional groups vibrations were found from Fourier transform-infrared (FT-IR) spectroscopy, whilst carbon graphite particles in thermoset renewable polymer matrix show sharp diffraction peaks through X-ray diffraction (XRD). Morphological view by optical microscopy images showed that the graphite particles are randomly distributed and oriented throughout the matrix. The optical study reveals that the absorbance was high in the ultra violet (UV) region which corresponds to wide band gap energy (4.10 to 3.98 eV). The electrical conductivity of TPG composites was found to increase with respect of graphite particles content. Obtained results indicate that the TPG composites are enhancing the key characteristics of the materials that are suitable for use in optoelectronic device applications in near future.
