Preparation of PVDF nanowire by Infiltration Method into Alumina Nanopores

Abstract

Poly (vinylidene fluoride) (PVDF) homopolymer nanowire array with the desired ferroelectric β-phase is fabricated in an anodic alumina porous (AAP) template. The results indicate that the hydrogen bonds between the AAP surface hydroxyl groups and PVDF molecules promote the formation of the β-phase The mechanism of polymer infiltration into the pores is also very important in order to obtain the desired one-dimensional nanostructures and to control their final morphology. In this study, infiltration method was explored with the aim to obtain different 1DPNs. It was shown that, with these infiltration methods, it is possible to obtain nanowire composed of polymer poly(vinylidene fluoride).
