摘　　要： 简述了纳米微粒表面修饰的重要性以及修饰方法,并指出制备核壳型纳米材料是一种重要的表面修饰方法。液相法制备核壳纳米粉体具有反应温度低、设备简单、能耗低的优点。而一步水热法在液相法中具有其它方法无法比拟的优越性。因此,重点讨论了一步水热法制备核壳纳米粉体的工艺流程和机理,并对一步水热法制备核壳型纳米材料进行了展望。 The importance of surface modification and modification methods are briefly stated. And the preparation of core - shell nano - material is an important technique for surface modification. Preparation of core - shell nano - material by liquid phase method has advantages of low reaction temperature, simple equipment and less consumption of energy. In which ,one -step hydrothermal method is more excellent for the preparation for core -shell nano - material. Therefore, the process and principle of one - step hydrothermal method is emphatically discussed. Furthermore, the prospect of this technique for core - shell nano - material＇s preparation is also presented.
