摘要以SDS(十二烷基硫酸钠)为表面活性剂,乙酸锌为前驱体,水-乙醇混合溶剂为反应介质,通过溶液化学方法制得ZnO纳米粒子。实验过程中考察了反应温度、表面活性剂与前驱体物质的量比等因素对ZnO纳米粒子制备过程的影响。通过紫外-可见吸收光谱(UV-Vis)、透射电子显微镜(TEM)、X-射线衍射(XRD)等对ZnO纳米粒子的结构和性质进行了表征。结果表明,控制合适的反应条件,可以得到量子尺寸效应较为明显的ZnO纳米粒子,ZnO纳米粒子具有球状形貌,尺寸在5~10 nm之间,且具有典型的纤锌矿晶体结构。抗菌实验结果表明,所合成的ZnO纳米粒子具有较好的抗菌性能。

Abstract: ZnO nanoparticles were synthesized by using sodium dodecyl sulfate as surfactant, zinc acetate asprecursor through wet-chemical route in ethanol-water mixer solvent. The effects of reaction temperatures and ratio of surfactant to precursor on the formation process for ZnO nanoparticles were studied. The structure and properties of the obtained ZnO nanoparticles were determined by using UV-Vis absorption spectrum, transmission electron microscopy (TEM) and X-ray differaction (XRD) methods. The results show that ZnO nanopariticles with an apparent quantum confinement effects could be prepared by controlling an ambient reaction conditions. The synthesized ZnO nanoparticles give a wurtzite crystalline structure and sphercial morphology with the size in the range of 5—10 nm. The ZnO nanocrystals have a better anti-bacterial property.

Key words: sodium dodecyl sulfate zinc oxide nanoparticles anti-bacterial property
