ABSTRACT
All high molecular weight polymers soluble in a solvent can be electrospun alone or by mixing with any type of miscible nanoparticles to produce polymeric nanofibrous membranes. The electrospinning process starts with the extrusion of a polymeric solution through a spinneret syringe needle. The difference between electrospinning and hollow fiberspinning is that the hollow fiber technique requires air or mechanical devices to create the extrusion force, while electrospinning needs a high voltage to charge the excluded solution. The ability to form porous electrospun nanofibers means that the surface area of the fiber mesh can be increased tremendously. The useful properties of electrospun nanofibrous membranes such as high absorbency, porosity, nanoscale interstitial space interconnectivity, and large surface area have meant that they have been used extensively in control of biological processes. Water purification requires several sequential steps to make collected water drinkable.
