Polymeric membranes are important separation techniques, these membranes are porous or dense and are categorized as symmetric or asymmetric membranes. These devices do separation base on size or structure of the substrates. Nowadayd, different methods are used to fabricate of nanofibrous membranes which attract the researchers’ attention. Nanofibers are prepared via various methods, such that electrospinnig is one of the appropriate, easy and economical methods to fabricate the nanofibers which have found many applications in different scientific fields, including fabrication of nanofibrous membrane for using in filtration process. The characteristics of these membranes are high porosity; of about 80%, highly interconnected pores and large ratio of surface area to volume. On the other hand, polyethersulfone is a polymer with special properties such as heat and chemical resistance as well as biocompatibility. In these membranes select of solvent, process and environmental conditions are many important that affected on nanifibrous substrate properties. Nanofibrous membranes could be improved whit the chemical and physical modification. In this paper, an overview of the process for electrospinning of polyethersulfone membrane has been investigated.
