本論文利用電火花放電法在無添加其他有毒化學物質下,於介電液中製備出奈米銀流體,並以麵團實驗來測試其不同濃度之殺菌效果。研究結果發現在加入總濃度100 ppm奈米銀的效果不佳,在加入總濃度60 ppm硝酸銀有明顯的效果,顯示其原因奈米銀解離率太差而導致效果不佳。利用電導導出銀離子並與碘結合為碘化銀,經霉菌抑菌實驗後得出碘化銀在六天後才生長出霉菌,抑菌效果優於單純的優碘。最後將銀的殺菌效能結合電紡,將高濃度的硝酸銀溶入10%的聚乙烯醇中,使紡出的電紡紗中混有奈米銀顆粒,並以U-V光譜機來驗證。電紡紗中的奈米銀會緩慢釋放銀離子,具有長效殺菌的功能。

Dielectric fluid used in this paper do not add other toxic chemicals, and the production of nano-silver fluid in the dielectric medium with a spark discharge method. Dough experiments to test its bactericidal effect of different concentrations. The results showed that: 100 ppm nano silver its bactericidal not good , 60 ppm silver nitrate its bactericidal well. The reason is that nano silver ion concentration is too low to cause bactericidal ineffective. The use of electrical conductivity method to synthesize silver ions and iodide ions become silver iodide. In bacteriostatic experiment: Six days later, the silver iodide grow mold, its bacteriostatic effect is better than Betadine. Finally, the combination of electrospinning nano silver. The high concentration of silver nitrate dissolved in 10% polyvinyl alcohol. Make nano silver particles coated electric spinning, then UV-Vis to verify. The Nano Silver electrospinning slowly releasing silver ions have long-lasting bactericidal function.
