Nanoscale multi-phase flow and its application to control nanofiber diameter

By Liu Yan-Qing, Zhao Lei and He Ji-Huan

Abstract

Nanoscale flows appear widely in nanofiber fabrication especially in electro-spinning, where a nanoscale jet is a multi-phase fluid including solvents and additives. This paper shows that the fiber morphology can be effectively controlled by adjusting the density of the multi-phase jet. TiO2 is used as an additive to produce polyacrylonitrile nanofibers by electrospinning; the results elucidate that uniform nanofiber can be obtained, and this phenomenon is explained theoretically
