A new procedure for transferring graphene from growth substrates (e.g., copper foil) is described. The method involves placing post-growth substrates (produced here using a Moorfield nanoCVD-8G system) at an interface between immiscible hexane and an aqueous etching solution. The etching solution removes the copper, leaving the graphene freely suspended. Application substrates are easily connected with the graphene by moving them through the liquid.
