Researchers from the Electronics and Telecommunications Research Institute and Konkuk University in the Republic of Korea have developed graphene enhanced fabrics that are able to detect lethal gases present in the air. The e-fabric alerts the wearer of danger by using an LED indicator. Cotton and polyester yarn is coated with a “nanoglue” known as bovine serum albumin (BSA). The fabric is then wrapped in a layer of graphene oxide sheets.
Graphene is an incredibly strong one-atom-thick layer of carbon, and is known for its excellent conductive properties of heat and electricity. The graphene oxide sheets adhered easily to the nanoglue. Testing showed that the fabrics were able to retain their electrical conducting properties even after a thousand consecutive bending, straightening and washing cycles. Finally, the graphene oxide strands were subjected to a chemical reduction process, which involves the gaining of electrons.
