Enhancement of electroactive phases of PVDF by mixing SiC nanowires for pressure sensing

Abstract

Poly(vinylidene fluoride) (PVDF) is one of the ideal materials for wearable pressure sensing owing to its excellent piezoelectric property, good flexibility, and easy fabrication processing. In this work, we mixed PVDF matrix with silicon carbide (SiC) nanowires acting as an efficient nucleating agent to transform the non-polar α phase to polar β and γ phases to improve the crystallinity of electroactive phases and enhance the piezoelectricity of PVDF thin film.
