摘要
在不同微波辐射功率、辐射时间、辐射温度、羽绒与纳米材料最佳质量比等实验条件下,研究了纳米二氧化钛对羽绒抗菌效果的影响,在所得最佳灭菌条件下,探讨微波协同纳米二氧化钛的最佳抗菌率。同时,进行纳米二氧化钛的回收实验,研究了多次回收的纳米材料抗菌效果的变化规律。结果纳米二氧化钛的最佳抗菌条件为:纳米二氧化钛与羽绒质量比为2∶1,微波时间为2 min,微波功率为100 W,微波温度为35℃,最佳抗菌效果为72.63%。随着纳米抗菌剂循环使用次数的增加,抗菌效果逐渐下降。
The antibacterial effect of nanometer titanium dioxide is studied under different experiment conditions, such as microwave radiation power, radiation time, radiation temperature, mass ratio of the nano material and feather. The antibacterial rate of nanometer titanium dioxide is also discussed under the best sterilization conditions. Meanwhile, the recycling of nanometer titanium dioxide is performed, which is used to discover the law of the sterilization rate of the recycled materials. The best antibacterial rate can achieve 72. 63% under the following conditions：2：1 mass ratio of nanometer titanium dioxide and feather,2 minutes of microwave time, 100 W of microwave power and 35℃ of microwave temperature. The antibacterial effect gradually declines with the increased recycle times of nanometer titanium dioxide.
