Scientists develop new nanomaterials for wearable electronics

According to the report from the US “Qiaobao.com” on June 13, scientists have developed a new type of flexible, retractable nanomaterial that can be used in wearable electronic products and other intelligent materials. According to reports, this film-type nanomaterial is composed of intricately turned nanofiber meshes, which are electroplated and attached to solid substrates. In addition to its flexibility and stretchability, it also has the advantages of transparency and high electrical conductivity. The material was developed in collaboration with scientists at the University of Illinois at Chicago and Korea University.

The researchers described the thin film material in Advanced Materials. Not only can it be used in the manufacture of wearable electronic products, its "Automatically connected nano-coppered wire mesh" technology can also be used to make flexible solar cells and roll-up touch screens.

At the press conference, Yalin, a professor of mechanical engineering at the University of Illinois at Chicago, said that the development of this transparent conductive material is a very important and very difficult task. In fact, scientists have previously developed a smart skin material, but its conductivity is at least 10 times lower than the latest retractable curved material. Tests have shown that the latest nanomaterial has no effect on its conductivity after stretching and bending.

The researchers used microfiber polyacrylonitrile electrospinning to create this “nanowire mesh” by first winding the microfiber roll around a solid substrate to form a complex network structure and then spraying it onto the wire mesh. Metal alloys and copper plating process. Yalin said that since the new material is transparent to the mesh, it can be attached to the surface of any object, including skin, leaves, or glass.
