An ultrathin film that is both transparent and highly conductive to electric current has been produced by a cheap and simple method devised by nanomaterials researchers from the Uni of Illinois at Chicago and Korea University. The film – actually a mat of tangled nanofiber, electroplated to form a “self-junctioned copper nano-chicken wire” – is also bendable and stretchable, offering potential applications in roll-up touchscreen displays, wearable electronics, flexible solar cells and electronic skin.
The new film establishes a “world-record combination of high transparency and low electrical resistance,” the latter at least 10X greater than the previous existing record, said Prof Sam Yoon, Korea Univ...
