中文摘要：
采用聚合物包覆热分解法化学工艺制备了纳米氧化锌，对其工艺进行系统的比较研究，对所得粉体进行XRD与SEM表征。发现利用该工艺所得粉体为六方晶系纤锌矿结构（空间群为P63mc）的纳米氧化锌。该方法制备的氧化锌衍射峰尖锐，表明此种方法合成的氧化锌结晶程度高。所得的氧化锌粉体XRD图谱中没有杂质衍射峰，说明产物纯度都很高。产品SEM表征结果显示了此工艺产物在形貌方面的高度一致性—为菊花状氧化锌纳米杆团簇，文中对产物形貌形成的原因做了详细的探讨。
英文摘要：
Nano ZnO is prepared by using the polymerized thermal decomposition. The structure evolution of ZnO is characterized by X-ray diffraction （XRD） and scanning electron microscopy （SEM）.The XRD patterns indicate all the as-synthesized powders are nano zinc oxide in hexagonal crystal wurtzite structures（SG：P63mc）, highly crystallization and highly purity. The ZnO powders in shape of the identical morphology, chrysanthemum-shaped nanorods cluster are observed from SEM images. In addition, the growth mechanism of ZnO crystal is discussed briefly.
