Preparation of Thermoplastic Polyimide Ultrafine Fiber Nonwovens by Electrospinning

Cailiao gongcheng, 2018
The superfine fiber of thermoplastic polyimide(LPI), whose average diameter ranges from 0.36μm to 1.47μm, was prepared through electrospinning with DMAc as solvent. It lays a good foundation for the mass preparation of LPI non-woven.
