A spider-inspired electrospinning for fabrication of polyvinylidene fluoride nanofiber membranes

Abstract

This paper is to mimic the long transporting process of proteins in the spider spinning, and a long and helical needle electrospinning technology is proposed, the polyvinylidene fluoride solution is used to study the effects of needle helix spirals on the micromorphology, mechanical property, electrical property, porosity, and hydrophobic property of polyvinylidene fluoride nanofiber membranes. The results showed that there is a threshold value for the helix spirals helical pitch, and its spider-inspired mechanism is discussed.
