Abstract
As a type of high-performance polymer, polyimide(PI) is widely used due to its excellent mechanical properties, high thermal stability, chemical resistance and radiation resistance. Electrospinning can continuously produce fibers with large specific surface area, high porosity, controllable morphology and diameters ranging from nanometers to several microns. The current status and the latest progress of electrospinning PI fiber membranes in various fields, including oil-water separation, air filtration, battery separator, resin toughening, sensor element, heat insulation materials were reviewed. The advantages and disadvantages of these applications were analyzed, and the challenges facing the development of PI nanofiber membranes in the future were summarized. The research provides references for expanding the application of PI nanofiber membranes with electrospinning.
