Abstract

We report a vibration-powered micro-generator, based on electrospinning polyvinylidene fluoride (PVDF) / graphene oxide (GO) composite nanofiber film. With the help of the electrospinning process, the PVDF nanofibers chemically wrapped by GO lamellae, in which the polar β-phase nanocrystals are formed and uniaxially self-oriented by the synergistic effect of mechanical stretching, high-voltage alignment, and chemical interactions. The special core-shell structure formed during electrospinning process gives nanofiber better piezoelectric properties. And the high piezoelectric coefficients nanofiber constitutes a film generator with better performance than previous work with similar sandwich structure.
