Special Issue Information

Dear Colleagues,

Electrospinning is a widely used technique in a variety of fields to fabricate nanofibers due to its versatility, scalability, low cost, and easy use. The resultant electrospun nanofibrous membranes offer several attractive features, including high surface area and porosity, intrinsic rough texture, controllable pore size/thickness, and interconnectivity. These outstanding properties make the electrospun nanofibrous membrane a versatile and promising material for environmental applications, including water treatment (e.g., micro/ultrafiltration, oil/water separation, heavy metal adsorption, photocatalysis), air purification (e.g., PM2.5 capture, masks development, indoor air filter), and chemical and gas sensing (e.g., ethanol sensor).

Over the past few years, we have been witnessing a surge in the design and engineering of nanofibrous membranes and structures to enhance their selectivity, permeability, wettability, and stability. These major breakthroughs lead the way to greatly improved process efficiency, reduced treatment cost and energy consumption, and many exciting new possibilities in a broad range of environmental applications.

This Special Issue of Membranes on "Electrospun Nanofibrous Membranes for Environmental Applications" highlights the latest developments of nanofibrous membranes (e.g., strategies, methods, materials), various nanofibrous-membrane-based environmental applications, and perspectives on the challenges to be addressed for further advancing nanofiber technology. Both reviews and original articles are welcome.

Wearable supercapacitors based on carbon materials have been emerging as an advanced technology for next-generation portable electronic devices with high performance. However, the application of these devices cannot be realized unless suitable flexible power sources are developed. Here, an effective electrospinning method was used to prepare the one-dimensional (1D) and nano-scale carbon fiber membrane based on potassium citrate/polyacrylonitrile (PAN), which exhibited potential applications in supercapacitors. The chemical and physical properties of carbon nanofibers were characterized by X-ray diffraction analysis, scanning electron microscopy, transmission electron microscopy, Raman spectroscopy, X-ray photoelectron spectroscopy, and the Brunnauer–Emmett–Teller method. The fabricated carbon nanofiber membrane illustrates a high specific capacitance of 404 F/g at a current density of 1 A/g. The good electrochemical properties could be attributed to the small diameter and large specific surface area, which promoted a high capacity. Full article
