摘要
新型纳米氧化铜不同于常规氧化铜,具有新颖的形貌和结构,其中包括氧化铜纳米颗粒、氧化铜纳米棒、氧化铜纳米片和氧化铜纳米梭等。新型纳米氧化铜具有优异的物理和化学性质,在众多领域里显示出广阔的应用前景,如应用于生物医药、传感器和催化材料等领域。纳米氧化铜的常规制备方法包括溶剂热法、热解法、微波法和磁控溅射法等。制备新型氧化铜纳米材料及其应用研究已经成为纳米材料领域的研究前沿和热点之一。
水热法由于其自身的优点,如反应可控、能耗较低等,越来越受到青睐,己经广泛用于纳米氧化物的制备,但是水热法在纳米氧化铜的制备研究上仍不成熟。
本论文简要介绍了水热法并分别以聚丙烯酸和丙烯酸-壳聚糖共聚物为模板合成球形氧化铜纳米颗粒以及对纳米氧化物的应用和现状进行研究;纳米氧化铜的性质、用途。重点研究了低温水热法制备超细纳米氧化铜,在较低的温度下、用较为便宜易得的原料成功的制备了超细纳米氧化铜。

Abstract
The new nano-copper oxides are different from the ordinary copper oxides, which have novel morphology and structures, including nanoparticles, nanorods, nanoplates and nanoshuttle of copper oxides, etc. They have excellent physical and chemical properties, and show good prospect of applications in so many fields, such as biomedicine, sensors, catalyst materials and so on. The conventional preparation methods of the nano-copper oxides include solvothermal, pyrolysis, microwave and ron sputtering methods, etc. The research of the preparation and applications of the new nano–copper oxides has e one of the forefront and hot topics in the namomaterial field.
Because hydrothermal method has a lot of advantage, such as, the reaction is controllable and the lower consumed energy et al. It was widely used in nano-oxide preparation. But the hydrothermal method has not been maturely studied in nano-copper oxides preparation.
In the paper we introduced the hydrothermal method and it’s used in nano-oxide preparation and the current situation. We also introduced the nano-copper oxides which are expected to have novel mechanical, catalytic and electronic properties. We essfully prepared ultra-fine nano-copper oxides by hydrothermal method at lower-temperature.
Key words:nano-copper oxides; hydrothermal method; preparation
