#Scientists print low cost radio frequency antenna with graphene ink (Nanowerk News) Scientists have moved graphene--the incredibly strong and conductive single-atom-thick sheet of carbon--a significant step along the path
Researchers from the University of Manchester, together with BGT Materials Limited, a graphene manufacturer in the United kingdom, have printed a radio frequency antenna using compressed graphene ink.
"These scanning electron microscope images show the graphene ink after it was deposited and dried (a) and after it was compressed (b). Compression makes the graphene nanoflakes more dense,
Graphene ink is generally low cost and mechanically flexible advantages it has over other types of conductive ink,
Graphene ink with binders usually conducts electricity better than binder-free ink, but only after the binder material,
which graphene ink can be printed because the high temperatures destroy materials like paper or plastic. The University of Manchester research team
together with BGT Materials Limited, found a way to increase the conductivity of graphene ink without resorting to a binder.
and the resulting"graphene laminate"was also almost two times more conductive than previous graphene ink made with a binder.
