【“耐撕”材料:纳米碳管薄膜】据国外网站engadget报道,华东理工大学一研发团队开发出纳米碳管薄膜,这款宏观材料继承了微观纳米碳管高强度(9.6Gpa)、高延伸率(8%以上)和优异导电性的特点。王健农教授介绍说该材料以平行放置碳原子的技术代替以往渗透、喷射等方法制作而成。

Carbon nanotube film is stronger and stretchier than Kevlar

Researchers at East China University of Science & Technology have finally managed to develop a macroscopic material that exhibits the same strength and pliability as individual nanotubes. In fact, their new carbon nanotube-based film that is five times stronger and 8 percent more pliable than any such material previously developed.

The secret is in how the nanotubes are arrayed, according to ECU professor Jian Nong Wang. By laying the tubes parallel to each other -- rather than spraying or filtering them on, as other methods do -- the ECU team was able to create the super-strong film. Their film has an average strength of 9.6 gigapascals -- far more than the 3.7 and 7 GPa that Kevlar and carbon fiber offer, respectively. It also offers superior electrical conductivity, making the new material ideal for use as a structural coating on vehicles and aerospace components or as next-generation electrodes.
