Abstract

Nano and porous materials with large surface area, high porosity, high surface reactivity, and strong adsorption properties have great application potential in energy and chemical industry, biological medicine, environmental science, defence engineering and numerous additional fields. Electrospinning is a convenient, direct and economical method of production of nano fibre materials. Porous fibre can be created by adjusting the process parameter of electrospinning or post processing after spinning. The introduction of porous structure into materials increases its surface area considerably and simultaneously enhances other properties. This indicates great potential for development in many fields and improves upon porous material application value. This project uses electrospinning to prepare polyvinylidene fluoride (PVDF) fibre and, post process, for PVDF porous fibre, utilising a combination of SEM, XRD and other tests to characterise properties. The effect and regularity of solution properties and processing parameters on prepared samples were studied along with experimental results and theoretical basis for preparation of electrospun PVDF fibres and fibres with porous structure. The main conclusions of this article are as follows: 1) Solvent concentration has a great influence on fibre morphology, enhancing PVDF concentration and resulting in increased regularity of fibre; meanwhile, fibre diameter will increase in correlation with the increase of concentration. 2) With the increase of acetone in DMF or NPM/acetone system, fibre morphology improves. 3) Assist solvent influences fibre morphology and samples created by DMF are superior to those created by NMP. There are fewer beads and fibres appear more regular. 4) Post processing parameter influences formation of pores, such as processing solvent, time, etc.
