摘　　要：检测了四针状氧化锌晶须、纳米氧化锌和普通工业级氧化锌的抗菌性能,比较了形貌和光照条件对ZnO抗菌性能的影响,并研究了ZnO对不同菌种的抗菌性能差异。结果表明,ZnO形貌对其抗菌性能有较大影响,有光条件下ZnO抗菌性能大于无光条件下,3种ZnO对大肠杆菌的抗菌性能均比对金黄色葡萄球菌好。The antibacterial activities of tetrapod-like ZnO whisker, nano-scaled ZnO and commercial ZnO particles were examined in this paper. Effects of morphology and light irradiation on antibacterial properties of ZnO were studied. The results indicated that morphology of ZnO has significant impact on its antibacterial property. Antibacterial property of ZnO under solar light irradiation is greater than that in dark. The antibacterial activities of ZnO on different bacterial species were also studied, and it can be seen that antibacterial properties of these three kinds of ZnOs on the E. coli are all better than that on the S. aureus.
