Special Issue Information

Dear Colleagues,

Water purification remains a hot topic in both academia and industry because of the ever-increasing freshwater crisis. Membrane-based technology provides good performance in water purification and has grown into the predominant strategy due to its suitability for continuous operation, low chemical mass, automated process control, and high selectivity. Nevertheless, the currently used membranes still do not meet people’s expectations because of their low water flux, thereby requiring high operating pressure that involves high energy costs. Therefore, researchers and engineers are exploring novel materials for membrane fabrications with enhanced performance for increasing cost and energy efficiency.

Electrospun nanofibrous membranes (ENMs) could provide high permeation due to their specific structures, including having a 3D interconnected web-like structure, high porosity, and tunable pore size, to name but a few. This has great potential for industrial applications where significant energy-saving benefits are necessary. In recent years, ENMs have been used in a wide area including microfiltration, ultrafiltration, nanofiltration, reverse osmosis, forward osmosis, and membrane distillation, and have displayed great potential for effective water purification. In some cases, they demonstrated obvious advantages compared with the traditional membranes.

The current Special Issue aims to seek the state-of-the-art in research progress and reviews in this field. The topic is very comprehensive, and may involve exploration of innovative raw materials for ENMs, membrane design and fabrication methodology, structure–performance relationship studies, membrane simulations and calculations, membrane process investigation, pilot tests, and more.

This study reports for the first time the preparation of an electrospun microfibrous mat of PIM-EA-TB. The electrospinning was carried out using a chloroform/n-Propyl-lactate (n-PL) binary solvent system with different chloroform/nPL ratios, in order to control the morphology of the microfibres. With pure chloroform, porous and dumbbell shape fibres were obtained whereas, with the addition on n-PL, circular and thinner fibres have been produced due to the higher boiling point and the higher conductivity of n-PL. The electrospinning process conditions were investigated to evaluate their impact on the fibres’ morphology. These microfibrous mats presented potential to be used as breathable/waterproof materials, with a pore diameter of 11 μm, an air resistance of 25.10−7 m−1 and water breakthrough pressure of 50 mBar.
