With the increasing application of electrospun nanofibers, the batch preparation of high-performance functional nanofibers containing nanoparticles has become a research hotspot. As the distribution uniformity of nanoparticles in functional nanofibers has a great impact on their performance, an electrospinning device with multiple air inlets, which has a copper porous spinneret, is proposed to obtain functional nanofibers with higher yield and more uniform distribution of nanoparticles. The mechanism of batch preparation of functional nanofibers containing ZnO nanoparticles by the device was studied through experiments and theoretical analysis. The experimental data are in good agreement with the theoretical analysis results, which showed that under the appropriate voltage (50 kV) and air flow (50 m/h), the device could keep ZnO nanoparticles contained in the spinning solution evenly dispersed during the spinning process, thus obtaining functional nanofibers with more uniform distribution of ZnO nanoparticles, whose quality and yield were higher than those prepared by other high-yield electrospinning devices.
随着电纺纳米纤维应用的不断增加，批量制备含纳米粒子的高性能功能纳米纤维已成为研究热点。由于纳米粒子在功能纳米纤维中的分布均匀性对其性能有很大影响，因此提出了一种具有多个进气口且带有铜多孔喷丝头的电纺丝装置，以获得更高产率且纳米粒子分布更均匀的功能纳米纤维。通过实验和理论分析研究了该装置批量制备含ZnO纳米粒子功能纳米纤维的机理。实验数据与理论分析结果吻合良好，结果表明，在合适的电压（50 kV）和气流（50 m/h）下，该装置能够使纺丝溶液中的ZnO纳米粒子在纺丝过程中保持均匀分散，从而获得ZnO纳米粒子分布更均匀、质量和产率均高于其他高产率电纺丝装置制备的功能纳米纤维。
