摘　　要：基于静电纺丝原理,建立了静电纺丝过程的仿真模型,对工作气体种类、环境温度对静电纺丝纤维直径的影响进行了模拟。通过创建封闭试验,对不同气体环境中电纺纤维的直径与形貌的影响进行了实验研究,探究了气体种类和温度对纳米纤维直径的影响。实验与仿真结果表明:气体分子量越大,射流半径越大,形成的纳米纤维直径越大,同时表面形貌越粗糙;在工作范围内,温度的提升将降低纳米纤维直径。Based on the principle of electrostatic spinning,a simulation model for electrostatic spinning process is established,and the influence of working gas type and ambient temperature on diameter of electrostatic spinning fiber is simulated.By creating a closed experiment,the influence of diameter and morphology of the electrostatic spinning fiber in different gas environments is studied experimentally,and the influence of the gas type and temperature on the diameter of the nanofiber is explored.The experimental and simulation results show that the larger the gas molecular weight,the larger the jet radius,the larger the diameter of the formed nanofibers and the rougher the surface morphology.Within the working range,the increase in temperature will reduce the diameter of the nanofibers.
