摘要
利用同轴静电纺丝技术制备出壳层为聚苯乙烯(PS),芯层为聚乙烯吡咯烷酮(PVP)的壳-芯结构复合纤维,通过除去芯层PVP,成功地制备出了PS中空亚微米纤维。并对其进行了TEM、SEM测试。结果表明,纺丝过程中内、外液流速比值K直接影响着复合泰勒锥的形成及复合纤维的微观形态,且复合纤维平均直径随K值的增大而减小。
In this paper, polystyrene （PS） hollow submicro-fiber has been successfully prepared by coaxial electrospinning technique with two polymer solutions, polystyrene/DMF and poly （vinyl pyrrolidone）/ethanol, followed by a removal of poly（vinyl pyrrolidone）. The PS hollow submicro-fiber was characterized by TEM and SEM. The results show that the relative （inner-to-outer） flow rate K value directly effects on the forming of compound Taylor cone and the morphology of the composite fibers. Moreover, the average diameter of the composite fibers decreases as K value increases.
