A team at Rice University (USA) has devised a method for making nearly transparent films of conductive carbon nanotubes, a goal sought by researchers around the world. They found that dipping slides into a solution of pure nanotubes in chlorosulphonic acid (CSA) left them with an even coating that, after further processing, had none of the disadvantages seen with other methods. According to the researchers, the method is scalable to high-throughput industrial processes such as slot, slide and roll coating. The films, which could potentially be used for touchscreens, remained electrically stable after more than three months, according to the team.
