The University of Cambridge have invented a graphene ink for PCB

In recent years this connection as graphene, has become increasingly popular in various fields of science. Scientists from Cambridge University, according to the publication Cosmosmagazine, recently came up with another use for this remarkable compound. Experts suggest using it to print circuit boards and even created a special "graphene ink".

As you know, graphene is the solid form of carbon molecules with a thickness of one atom, where the atoms are arranged in a two-dimensional hexagonal lattice. Despite the small thickness, fiber graphene flexible and durable, and also have good conductive properties. As stated by one of the study's authors, James McLeod,

"We are working to create an electrically conductive ink for printing flexible electronics of all types. Our graphene ink is, in fact, the powdery graphene, suspended in alcohol, which can be used to print electronic circuits. It was the first case when we used alcohol to create the ink, and I was struck by how it is fascinating when mixed."

the world's first graphene-based ink

The ink itself is produced by passing the graphite under high pressure through micro-capillaries of the diamond, which break the graphene, thus separating the layers, which leads to the formation of a smooth conductive material in solution. The resulting material can be used for application to any surface, including for the production of printed circuit boards.
