碳纳米管/磁性纳米粒子复合技术的研究进展

碳纳米管作为一种新型准一维功能材料已成为物理、化学和材料科学等领域的研究热点.由于缺乏微观上的加工处理方法,碳纳米管的应用受到一定程度的限制.磁性纳米材料由于其特殊的物理化学性质在存储器、传感器和环境保护等方面得到了广泛的应用.将磁性纳米粒子与碳纳米管复合不但可以使碳纳米管功能化改性,而且还可通过复合纳米管对磁场的响应对其进行加工处理.综述了碳纳米管与磁性粒子复合的制备技术,并展望了磁性复合碳纳米管的应用及其前景.

Research Progress on Carbon Nanotubes/Magnetic Nanoparticles Composites

As a one-dimensional novel functional material, carbon nanotubes(CNTs) have attracted considerable attention in physic, chemistry and material fields. A variety of potential CNTs applications exist, however, technology development is in part hampered by the lack of effective means for manipulating these materials at very fine scales.Magnetic nanomaterials are widely used in data storage, sensors and environmental protection because of their unique physical and chemical properties. Introduction of magnetic nanoparticles not only gets the CNTs functional modification, but also offers a potentially simple means for controlled manipulation. The synthesis methods of CNTs/magnetic particles composites are summarized,and the future application of CNTs/magnetic particles composites is prospected in this paper.
