Graphene Nanolayers Reinvented: The Key to Advanced Electronics

A new method using rotaxane structures to cross-link graphene layers enhances the flexibility, strength, and conductivity of graphene films, with potential applications in advanced electronics and mechanical tools. Credit: SciTechDaily.comGraphene, composed of layers of carbon atoms arranged in a honeycomb pattern, is recognized as a supermaterial due to its exceptional conductivity and mechanical advantages.

A molecular “anchor” was attached to both the axle and wheel by a linker. The graphene was oxidized to make graphene oxide, which forms a variety of oxygen-containing groups on both sides of the graphene layer. These include carboxyl groups, which can bind to the OH groups . This reaction allows the wheel and axle to cross-link the layers, after which the graphene oxide is reduced back to graphene.
