摘 要:设计并制造了一种便携式微型静电纺丝仪,并用于纳米纤维基速溶补水面膜的开发,同时利用Comsol有限元分析软件进行静电场模拟,确定制备纳米纤维膜的最优工艺参数。结果表明:微型静电纺丝仪的圆锥状纺丝头直径0.6 mm、长度8 mm、接收距离为120 mm、纺丝电压为25 kV、平均电场强度为1.2×10^(8) V/m时,纺丝效果最佳。在此条件下,将聚乙二醇单甲醚十四醇(PEG-14M)、透明质酸钠(HA)和1, 3-丁二醇(1, 3-BDO)按40∶1∶4的质量比例配置纺丝液制备纳米纤维膜,并对纤维膜的性能进行分析。当PEG/HA/BDO的溶液质量浓度为10%,供液速度0.2 mL/h,接收距离200 mm,纳米纤维膜的纤维平均直径为284.8 nm,变异系数为19.8%,表明纤维直径分布均匀。将纳米纤维膜制成面膜进行皮肤模拟测试,喷上去离子水后,纳米纤维膜在6 s内迅速溶解,同时皮肤水分质量分数高达38%,与空白组对比可知该面膜的补水增幅为81%。研究表明,该微型静电纺丝仪使用便捷,通过其制备的纳米纤维膜具有速溶补水的优势,在补水面膜领域具有潜在的应用价值。In recent years,with the rising living standards in China,consumer attitudes have gradually shifting.Women and even men have an increasing high pursuit of skin care,and the consumer base for facial masks has been expanding.Owing to their high porosity,large specific surface area,high air permeability,and small pore size within the fibers,nanofibrous membranes prepared by electrospinning technology have the characteristics of great specific surface area,excellent porosity,perfect adhesive biocompatibility,good moisture retention and water holding capacity.Therefore,it is of great significance to build a micro-typed electrospinning instrument to prepare nanofiber-based facial masks to occupy the high-end facial mask market in China.The micro-typed electrospinning instrument studied in this project is small in size,convenient to carry or move,and the charge will tend to gather at the position with the largest curvature and the strongest adsorption force(namely needle tip).It enables continuous and stable electrospinning,and it does not require disassembly of the device for battery replacement,so it can be directly charged and used,and the electrospinning can be used continuously.It marks a significant advancement in the nanofiber production technology via electrospinning,and its application in medical aesthetic masks promises to be a breakthrough in the field of nanofiber masks.Based on the design scheme of a mobile electrospinning device with current extraction,this study used COMSOL finite element analysis software to analyze and discuss the electric field uniformity of the liquid surface at the outlet of the nozzle with different spinning-methods,explored the influence law of electrospinning voltage and collection distance on the electric field strength,and determined the optimal data of spinning-methods.Soluble nanofiber facial masks were fabricated by using the electrospinning method,and the effects of different solution ratio,applied voltage,collection distance and liquid supply speed on the surface morphology
