Patent number: 7988896Abstract: A method of preparing a carbon nanotube/polymer composite material is provided. The method includes (a) providing a carbon nanotube-based film and a pre-polymer solution; (b) placing the carbon nanotube-based film at a bottom of a container, and pouring the pre-polymer solution in the container; and (c) polymerizing the pre-polymer solution and simultaneously integrating the pre-polymer solution with the carbon nanotube-based film. As such, a carbon nanotube/polymer composite material, including the polymer-impregnated nanotube layer and an upper polymer layer, is obtained. A multi-layer composite can be produced by essentially repeating this process, using the upper polymer layer as the base layer for the formation of the next layer set thereon.Type: GrantFiled: July 31, 2007Date of Patent: August 2, 2011Assignees: Tsinghua University, Hon Hai Precision Industry Co., Ltd.Inventors: Qiu-Cen Zhang, Peng-Cheng Song, Chang-Hong Liu, Shou-Shan Fan

Publication number: 20080241695Abstract: The present invention relates to a carbon nanotube composite electrode material, a method for manufacturing the same and an electrode including the carbon nanotube composite material. The carbon nanotube electrode material includes carbon fibers and carbon nanotubes. The carbon fibers constitute a network structure. The carbon nanotubes are wrapped around and adhering to the carbon fibers. Because a diameter of the carbon fibers is about 100 times larger than that of the carbon nanotubes, gaps between the carbon fibers are also larger than that between the carbon nanotubes such that electrolytes can easily penetrate into the carbon fibers and come into contact with all or nearly all of the available surface area of the carbon nanotubes. In other words, an effective surface area of the carbon nanotubes is improved, and capacity of electrode material is also improved.Type: ApplicationFiled: December 5, 2007Publication date: October 2, 2008Applicants: TSINGHUA UNIVERSITY, HON HAI PRECISION INDUSTRY CO., LTD.Inventors: PENG-CHENG SONG, DING WANG, CHANG-HONG LIU, SHOU-SHAN FAN
