‘Nano Paper’ That Can Conduct Electricity

Dec 09, 2009

Research team from Stanford University have transformed paper into an electricity storage device

The research group, led by Yi Cui, professor of materials science and engineering at Stanford, has created ink made from carbon nanotubes and silver nanowires. When the paper is dipped in the nano-enhanced ink and then baked, it transforms into a black paper that can act as a battery or supercapacitor. The ink-treated paper is able to hold an electric charge in any form, whether it lies flat or crinkled. Professor Cui notes that the ‘nano paper’ could have applications in electricity storage devices connecting to electrical grids, and could also be used in hybrid electric cars.

能导电的“纳米纸”

来自斯坦福大学的研究小组声称能将纸张转变成为电能贮存装置

    由斯坦福大学材料科学与工程教授崔毅（音译）领导的研究小组制备了由碳纳米管与银纳米线所组成的墨水。当纸张浸入这种被纳米增强的墨水中并烘干后，得到的一种黑色纸能作为电池或者超级电容器使用。经过这种墨水处理过的纸不管是平整的还是起皱的都能够贮存电荷。崔教授指出，这种“纳米纸”能应用于连接到电网上的电贮存装置中，也可以用于混合动力车辆。
