中文摘要：

本文通过原位合成方法制备了磁性改性四针状氧化锌晶须（M-ZnOw）,并通过焙烧处理对M-ZnOw的成分进行了调整。在此基础上,对M-ZnOw的微观形貌、成分、磁学性能进行了表征,结果表明M-ZnOw保持了四针状氧化锌晶须（T-ZnOw）的四针状结构,且在晶须表面均匀生长有磁性纳米颗粒,M-ZnOw可在室温下表现出超顺磁性、铁磁性等磁学性能。对M-ZnOw原位合成工艺的进一步研究结果表明,PEG在ZnO和磁性纳米颗粒间起到了桥联作用。

英文摘要：

Magnetic modified ZnO whisker （M-ZnOw） was prepared through in situ synthesis, and the components of M-ZnOw were modulated by bake treatment. Furthermore, the morphology, components and magnetic properties of M-ZnOw were characterized, and the results show that M-ZnOw kept the tetra-needle-like morphology while the magnetic particles uniformly generated on the whisker＇s surface; the results also indicate that M-ZnOw appeared such properties as superparamagnetic and ferromagnetic property. Further investigation on the procedure of the in situ synthesis demonstrates that PEG played a bridging role between ZnO whisker and nanoscale magnetic particles.
