Piezoelectricity and electrochemical effect of PVDF thermoplastic-based composites

ABSTRACT

Polyvinylidene fluoride (PVDF) is a very high rendering polymer with a great performance of actuation and exceptionally good chemical and thermal resistance. The polymerisation of vinylidene difluoride produces PVDF, which is a highly non-reactive thermoplastic fluoropolymer. Due to its higher flexibility and piezoelectric properties, fabrications of PVDF-based nanocomposites are much in demand today and have found lots of applications in next-generation sensing objects such as promising piezoelectric energy harvesters (nanogenerators), energy storage devices, sensor systems, and biomedical devices. In this work, a brief review of the nature and characteristics of PVDF-based polymers has been discussed. Besides some manufacturing methods for nanocomposites, ways to improve PVDF phase crystallinity (α, β) and nanocomposite qualities are also reviewed.
