Pbo/Graphene Added Beta-Pvdf Piezoelectric Composite Nanofiber Production

Abstract

In this study, composite nanofibrous piezoelectric materials were produced. A solution of polybenzoxazole (PBO) with hydroxamoyl chloride was prepared with the sol-gel method using PBO, PVDF, and graphene. Composite nanofibrous materials were then fabricated from the produced solution using the electro-spinning method. The subsequent characterization of the piezoelectric materials was conducted using XRD and FTIR analysis. The mean radius of the fibers was calculated using SEM. Based on TGA and DSC analysis, it was found that the thermal resistance increased by around 20 degrees C with the addition of PBO. The surface morphology of the fibers was examined using AFM analysis. Even when pressing and polarization were not applied to the fibers, electricity was able to be generated. The oscilloscope showed that fibers 0.02 mm and 0.06 mm generated maximum 60 V and 9.68 V of electricity, respectively. An electric circuit was designed and an LED light run using the generated electricity.
