气泡静电纺丝是大规模生产纳米纤维的一种新颖而强大的方法。本工作建立了非线性数学模型来分析聚合物溶液的表面张力对气泡静电纺纳米纤维直径的影响。然后在气泡静电纺丝过程中使用具有不同表面张力的 36wt% 聚乙烯吡咯烷酮 (PVP) 溶液评估模型的有效性。实验数据与模型预测吻合良好，表明分析模型具有较高的准确性，使其能够用于静电纺丝过程。概述了纳米纤维在防爆背心中的潜在应用。
Bubble electrospinning is a novel and powerful approach for mass production of nanofibers. In this work, a nonlinear mathematical model is established for analyzing the effect of the surface tension of polymer solution on the diameter of bubble-electrospun nanofibers. The validity of the model is then evaluated using 36wt% Polyvinylpyrrolidone (PVP) solutions with different surface tension in bubble electrospinning process. The experimental data agree well with the model prediction, suggesting that the analytical model exhibits high accuracy which enables it to be used for the electrospinning process. The potential application of nanofibers to explosion-proof vest is outlined.
