A synthetic material made from a protein in spider silk and laced with graphene can rapidly repair itself and form healable electrical circuits.
at the National Taiwan University and his colleagues collected silk from giant golden orb-weaver spiders (Nephila pilipes) and dissolved it in a chemical called hexafluoroisopropanol.
They dried the solution to create a thin film and used a razor blade to make a small cut in it, about 30 micrometres wide. When they added a…
