Highly conductive graphene-coated silk fabricated via a repeated coating-reduction approach

A repeated coating-reduction approach was developed to directly immobilize graphene nanosheets on silk for high conductivity. The as-prepared highly conductive graphene-coated silk fabrics (1.5 kΩ sq −1 ) and fibers (3595 S m −1 ) are promising as the functional supporting matrix and conducting fabrics/wires in future wearable electronics.
