Abstract

Mechanical property is one of the most important properties of nanofiber membranes. Electrospinning is widely used in the preparation of nanofibers due to its advantages such as good stability and easy operation. Compared with some nature silk, the mechanical properties of nanofibers prepared by electrospinning are poor. Based on the principle of vortex spinning and DNA structure, this paper designed an air vortex electrospinning device that can control the structure of macromolecular chains in nanofibers. When a weak air vortex is generated in the electrospinning process, the macromolecule chains will entangle with each other and form a DNA-like structure so as to improve the mechanical property. In addition, when a strong air vortex is generated during the electrospinning process, the nanofibers will adhere to each other, thereby enhancing the mechanical property and enlarging the pore size.

Summary

Introduction

Vortex spinning is a pneumatic spinning method and widely used in the textile industry [1,2,3]. It can be viewed as a refinement of jet spinning, or a natural development in fascinated yarn technology, which enables the yarns to exhibit better evenness and tenacity values [4,5]. How to further improve the mechanical property of nanofiber membrane has always been an important problem for researchers. This paper aimed at demonstrating that the air vortex has an important effect on macromolecule chains in a nanofiber and between nanofibers in the electrospinning process. As to improve the mechanical property of nanofiber membranes
