摘　　要：利用高温分解法合成氧化锌/二氧化钛复合材料,并测定在不同微波条件下,该复合材料对羽绒的抗菌效果,探讨了最佳抗菌工艺条件(羽绒与复合材料的质量比、微波功率、微波温度和微波时间);同时也对所合成复合材料进行回收,研究其回收后抗菌效果。实验结果表明,微波协同氧化锌/二氧化钛复合材料的最佳抗菌工艺条件为:羽绒与复合材料的质量比1∶1,微波功率400 W,微波温度47℃,微波作用时间1 min,最佳抑菌率为78.89%,一次回收抑菌率为64.71%,至少可回收2次。The zinc oxide doped titanium dioxide composites （ZnO/TiO2 ） were synthesized by hydrolysis method. Under different microwave conditions, the antibacterial effects of the prepared composites were tested to find the optimum process conditions of the antibacterial test including the mass ratio of the composites and eiderdown, radiation power, radiation temperature and radiation time. Meanwhile, the composite materials was recycled and the antibacterial effects of the recycled composites were studied. The results revealed that the optimum antibacterial conditions were as follows： the mass ratio of ZnO/TiO2 composites and eiderdown 3： 1, radiation power 400 W, radiation temperature 47 ℃ , radiation time 1 min. And the highest inhibition rate was 78.89%. The inhibition rate of the prepared composites after the first recycling was 64.71%. However, the ZnO/TiO2 composites can be recycled at least two times.
