Abstract

Polyimide nanofibers were obtained by electrospinning a solution of poly(amic acid)(PAA), a precursor of polyimide(PI) prepared in the laboratory, in dimethylacetamide(DMAc) at 14kV, followed by thermal imidization. Mechanical property of the resulting nanofiber non-woven membranes was investigated by tensile tests. Chemical structure and surface morphology of the non-woven mats were characterized by Fourier transform infrared spectroscopy (FTIR) and scanning electron microscopy (SEM) as well as atomic force microscope (AFM) respectively
