Effect of Concentration on Fibers Obtained by Electrospinning Method

فاقد چكيده فارسي

The electrospinning method is a variation of the electrospraying process. Both of these methods use high voltage to induce the formation of a liquid jet. In electrospraying, a solution of low viscosity is used to create an electrified jet that forms small droplets upon varicose break-up [2]. In this article we came up with polyvinylpyrrolidone(PVP( in different concentrations in ethanol solution, and we process the electrospinning process with these solutions at flow rate, voltase and spray gap to a certain collector. It can be seen that by increasing the concentration of the resulting solutions, the diameter of the fibers obtained from them also increases.
