Electrospinning Basics

Science and Technology of Polymer Nanofibers. By Anthony L. Andrady Copyright 2008 John Wiley Sons, Inc. 

Experimentally, an electrospinning apparatus consists of three basic components  

The principle variables that govern nanofiber quality (or determine if electrospinning will occur at aU) are the average molecular weight of the polymer, the nature of the solvent, and the magnitude of the electric field used to induce electrospinning.

Basically, electrospinning process parameters can be classified into three differenttypes solution, process, and ambientparameters. Viscosity, conductivity, and surface tension which affect instantly dimensions and morphology of fiber. Viscosity is one of the most important solution parameters.

Electrostatic fiber spinning, also known as electrospinning, is a versatile method to prepare continuous fibers with diameters ranging from several microns down to 100 nm through the action of electrostatic forces (Huang et al. 2003 Greiner and Wendorff 2007). Basically, the electrospinning process consists in the uniaxial... 

Many basic properties are harmonious by adjusting electrospinning parameters such as voltage, flow rate and others, and it can offer in-depth inside into physical rmderstanding of many complex phenomena which cannot be fully ejqrlain [9].
