Liquids are essential for most of the lives and activities on earth, where liquid filtration is an important tool to remove undesired suspended solids, emulsified particles, dissolved molecules, and ions from liquids by separating the permeate from the unwanted impurities through filters. Electrospun nanofibrous membranes (ENMs) have been developed as filtration media having unique advantages over traditional membranes, due to high porosity, interconnected pore structures, large surface-to-volume ratio with capability for chemical/physical functionalization, and cost-effectiveness. The new fibrous membrane format has been used in many applications, including filtration, (membrane) distillation, and pervaporation.

Polyacrylonitrile nanofibers ( PAN-nfs) are one of t he most studied nanofibres because of their excellent characteristics, such as good mechanical strength, chemical resistance, and good thermal stability. Due to the easy dissolution in polar organic solvents, PAN-nfs are mostly produced via electrospinning technique. The electrospun PAN-nfs surfaces are relatively in-active and hydrophobic, and, therefore, hinder some potential applications; however, chemical surface modification reactions, such as amination, reduction, hydrolysis, and amidoximation, have been carried out on them. These reactions bring about functional groups, such as amine, hydroxyl, carboxylic, imine etc, to the surface PAN-nfs and invariably make their surfaces active and hydrophilic. The surface-modified PAN-nfs have been used as supports for organic compounds, enzymes, and antibodies in biological studies. They have also been used for immobilization of various organic ligands for adsorption of metal ions in water. Furthermore, because of their ability to complex metal ions, several surface-modified PAN-nfs have also been used as supports for transition metal catalysts in Fenton's chemistry.

“…Anti-microbial nanofibers can be synthesized by incorporating nanobiocides such as silver nanoparticles into the nanofibers. The synthesis of nanofibers containing metal nanoparticles is well researched because of the advantages involved with combining the functional properties of metal nanoparticles with the widely applicable properties of nanofibers [4].…”

Anti-microbial nanofibers can be synthesized by incorporating nanobiocides such as silver nanoparticles into nanofibers. Bacterial contamination of water is a serious public health concern because it causes numerous diseases and some aesthetic problems such as malodor in water. Durable antibacterial Ag/polyacrylonitrile (Ag/PAN) hybrid nanofibers were prepared by electrospinning. SEM and EDX spectra were used to study the morphology and surface elemental composition of the nanofibers. The Ag/PAN nanofibers exhibited slow and long lasting silver ion release. The resultants polymers were then tested for their ability to destroy bacteria in water; antimicrobial tests indicated that the prepared nanofibers have a high bactericidal effect. Accordingly, these results highlight the potential use of these nanofibrous mats as antimicrobial agents.
