This attention is justified by the high specific surface area and high porosity, diversity of physical/chemical modification, and simplicity of hybridization. This review summarizes the state-of-the-art progress on the fabrication of polymeric nanofibers(PNFs) with particular emphasis on their scalable productions for emerging applications. First, the engineering processes and equipment for PNFs production are briefly introduced, and the effects of the polymer precursors, operational parameters, and environmental conditions on the nanofiber’s formation are illustrated. The past achievements and current challenges of PNF preparation in industrial production are also discussed. Hybridization methods to prepare multifunctional composite nanofibers are also reviewed, including organic incorporation modification, loading functional inorganic nanomaterials, and biological active components on/into nanofibers. Given these hybridizations and functions, a variety of applications are then discussed, focusing mainly on environmental and biomedical applications. Finally, conclusions are drawn and prospects are given according to the reviewed research.展开更多
