A group of researchers led by YiCui, a professor of materials science and engineering at Stanford, demonstrated how to use inks containing carbon nanotubes and nanosilver wires. Once this ink droplet is baked on paper, the plain paper becomes a black paper that can act as a battery or super capacitor. Even if it is bent, curled or wrinkled, this paper has the ability to store electricity.
This ink does not look like ordinary Indian ink, because Cui's ink is also made of carbon, but it is a carbon nanotube. Cui and his research team tried the ink on plastic, but found that paper is more suitable, because it can absorb water and wrinkle does not matter, this ink can also be used as a conductive wall paint. Cui said that the nano-ink paper can be applied to a power storage device connected to the grid and can be recharged 40,000 times. This nanomaterial is more conductive than normal materials. Cui believes that this type of paper can become a portable storage device for wind, solar energy, etc. in the future to solve the problem of excess power storage. It can also be applied to hybrid vehicles or electric vehicles.
Inklight or printing has become a method often used by scientists when nanotechnology is used to transfer unusual substances to general objects. Innovalight has succeeded in developing a patented ink that can be used to make ink jets. In 2007 IBM and ETHZurich researchers also developed a way to "print" molecules.
