Effect of UV/ozone treatment on surface hydrophilicity and humidity sensing properties of PVDF-BaTiO3 composite films

Abstract

In this research work, we have studied the impact of UV/ozone treatment on the hydrophilicity of the PVDF-BaTiO3 nanocomposite film. We have prepared the nanocomposite solution by mixing PVDF (2.5 wt% kept constant) and BaTiO3 nanoparticles (0.25 wt%, 0.5 wt%, and 1 wt% varied concentration). The spin coating technique has been used to deposit the nanocomposite film on the Interdigitated ITO electrode.
