摘要: 利用静电纺丝技术制备了具有微孔结构的聚醚酰亚胺(PEI)纳米纤维,在此基础上采用同轴共纺技术获得了有机玻璃/聚醚酰亚胺(PMMA/PEI)纳米复合纤维,考察了不同的纺丝工艺参数对PEI和PMMA/PEI纤维形貌的影响. 实验结果表明,在低浓度下单纺可获得直径0.05~0.5 mm的PEI微孔纳米纤维,使用同轴共纺技术能获得表面光滑的PMMA/PEI复合纳米纤维;经过4 MPa压置处理10 min的复合纳米纤维薄膜的拉伸强度随PEI含量的增加有所提升.

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 electrospinning. Furthermore, the tensile strength of composite films treated under 4 MPa pressure for 10 min rose with the increasing content of PEI.

Key words: polyetherimide, polymethyl methacrylate, coaxial electrospinning, fiber
