Research on Magnetism and Electrochemical Capacity of Iron-nickel Alloy and Carbon Nano Tube Composite Material

在实验室条件下制备了铁镍原子物质的量比分别为1:1和1:2的铁镍合金碳纳米管复合材料,并通过材料磁强测试计和循环安培测试法研究了铁镍合金粒子对碳纳米管进行填充所得复合材料的磁性能和电化学性能.研究结果表明:铁镍合金粒子填充碳纳米管所得复合材料是软磁材料,复合材料的磁化强度与铁镍合金粒子的填充量呈正相关,铁镍的比例会影响复合材料的饱和磁化强度;铁镍合金粒子填充碳纳米管所得复合材料表现出了典型的电催化性能,复合材料的电催化性能高于纯金属单质和纯碳纳米管材料,电解液p H值会影响复合材料的电催化性能.

Under the condition of laboratory, the hl and 1：2 iron-nickel alloy and carbon nano tube composite materials were made. The cyclic AMP method and magnetic testing meter were used to research the magnetism and electrochemical capacity of the composite.The results show： the composite is a soft magnetization material and the magnetization is related to the Ni amount. The Iron-nickel Alloy and Carbon Nano Tube Composite has a typical electro-catalysis and the electro-catalysis is influenced by the pH and alloy proportion.
