Description
Summary:碩士 === 國立臺北科技大學 === 電機工程系所 === 102 === 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.
