Dispersal of Polythiophene Nanoparticles for Preparing Thin Films

Abstract

In recent years, polythiophene-based nanoparticles have received a lot of attention due to their impressive properties. These properties include charge conduction in the oxidized/reduced states, light absorption/emission at an appropriate wavelength, geometrical adaptability, thermal/chemical stability, and solubility in common solvents. This spin coating process uses a thin film of polythiophene nanoparticles distributed in an organic solvent over a glass substrate. Polythiophene polymer production was confirmed by Fourier Transform Infrared spectroscopy (FTIR) and Raman spectroscopy measurements used in characterization investigations of the produced thin film. X-ray diffraction (XRD) and ultraviolet-visible (UV-vis) spectroscopy are employed to investigate the structure optically and the surface morphology.
