Electrospun polymer nanofibrous membrane for filtration.

Modern processing techniques in fiber technology combined with novel polymer materials results in new products. Electrospinning is one of the methods to prepare nanofibers of polymer or polymer composite materials. Membranes made out of these nanofibers can be used in variety of applications like filtration, tissue engineering, drug delivery etc. The membrane properties are governed by their surface properties and pore distribution, as well as their morphology. In this paper we are reporting the preparation and characterization of sulfonated poly(ether ether ketone) nanofibers and membrane made out of these fibers. The surface and cross sectional morphologies are characterized using scanning electron microscopy. Further the membrane is characterized for pore size distribution and pure water permeability. This work can be extended for exploring the use of electrospinning nanofibrous membranes for filter application.
