Preparation and Characterization of Porous PEI and PMMA/PEI Composite Fiber
|
Abstract:
Porous polyetherimide(PEI) and polymethyl methacrylate(PMMA)/polyetherimide(PEI) nanofibers were prepared through solution electrospinning and coxial electrospinning.The effects of electropsinning parameters on the morphology and diameters of PEI and PMMA/PEI fibers were studied.The results demonstrated that porous PEI fibers with the diameters from 50 to 500 nm were obtained by electrospinning in a low concentration, while PMMA/PEI fibers with smooth surface morphology were collected using coxial electrosp...
