摘要

研究静电纺丝的溶液性质,探讨溶液黏度、表面张力和电导率3种溶液性质间的交互作用及其对静电纺纳米纤维形貌及直径的影响.利用扫描电子显微镜(SEM)对制备的纳米纤维的表观形态和直径进行表征,采用SPSS分析软件对聚合物溶液多种性质的交互作用进行分析,并得出纳米纤维直径的预测公式.通过调整溶液性质,可实现对静电纺纤维形貌及直径的调控,这对于纳米纤维可纺性的研究以及结构调控具有重要意义.%This paper studied the interaction among electrospinning solution properties including viscosity,surface tention and conductivity on the apparent morphology and diameter of the electrospun nanofiber.The nanofiber morphology and its diameter were characterized by scanning electron microscope(SEM).SPSS software was used to analyze the interaction of solution properties and the forecast formula of nanofiber diameter was obtained.Adjusting the solution properties,can realize the control on the morphology and diameter of electrospun fibers,which is of great significance for the study of nanofiber spinnability and structural adjustment.
