摘要: In this paper, polyimide (PI) nanofibers with diameters of 300–400 nm are successfully produced via electrospinning methods. Electrospinning parameters such as polymer concentration, applied voltage, feed rate, and the needle-to-collector distance have been studied systematically to investigate their effects on morphology. The smooth-surfaced uniform ranging from 300 400 nm can be obtained at optimal parameters, further discussed herein. synthesized PI show improved thermal stability a high hydrophobicity maximum contact angle 140.7° low surface energy 3.12 mN · m−1, indicating potential applications self-cleaning materials, solar panel cleaning, window glass cements.
