Abstract

Due to the rapid technological developments, optoelectronic materials have attracted much attention. However, designing low-cost materials with outstanding optical properties is still an open challenge. In this regard, we demonstrate the opportunity to synthesize a new optically active composite material made of PVC, PVP, and BiVO4. The incorporation of BiVO4 into the PVC/PVP matrix enhanced the optical properties of the polymers, shifting the absorption edge from the UV to the visible light region with a decrease in the direct band gap from 4.9 to 2.18 eV and the indirect band gap from 5.17 to 3.04 eV. Additionally, the incorporation of 0.6 wt% BiVO4 resulted in a slight decrease in the water contact angle from 92.47 ± 0.23° to 86.49 ± 0.24°, which did not significantly change the hydrophobicity of the polymeric blend. Furthermore, the addition of 0.6 wt% BiVO4 to the PVC/PVP blend improved the thermal stability of the composite, with a weight loss of 72.6% at 780 °C. These results indicate the potential of the synthesized nanocomposite for optoelectronics applications.
