Publication number: 20120149547Abstract: A method for making a carbon nanotube based composite is provided. In the method, carriers, solution containing metal ions, and a carboxylic acid solution are mixed to form a mixed solution containing a complex compound. A reducing agent is added into the mixed solution. The metal ions are reduced to metal particles absorbed on the surface of the carriers. The carriers having the metal particles absorbed thereon are purified to obtain the carbon nanotube based composite.Type: ApplicationFiled: March 22, 2011Publication date: June 14, 2012Applicants: HON HAI PRECISION INDUSTRY CO., LTD., TSINGHUA UNIVERSITYInventors: JIAN-WEI GUO, LI-NA ZHANG, LI WANG, CHENG WANG, XIANG-MING HE, ZHI-XIANG LIU
