Electrospinning is a simple and versatile method for fabricating continuous fibers with diameters ranging from micrometers to several nanometers that is useful in water purification. Highly porous electrospun nanofibrous membranes currently gain considerable interests in water filtration applications. Poly(ethylene terephthalate) (PET) was selected as the polymer to synthesize the nanofibrous mats, due to its low cost to synthesis, high porosity and strength  of membrane characteristics, and good electrospinning properties. The PET nanofibrous mats are obtained by electrospinning PET solutions in trifluoroacetic acid/dichloromethane. The goal of the present study is to further the understanding of relationships between the structural parameters of PET electrospun nanofibrous membranes (i.e., average fiber diameter, fiber diameter size distribution, membrane thickness and porosity) and microfiltration performance for water purification.
