摘要
Methods of delaminating a graphene film (60) from a metal substrate (50) are disclosed that substantially preserve the metal substrate. The methods include forming a support layer (80) on the graphene film and then performing an electrochemical process in an electrochemical apparatus (10). The electrochemical process creates gas bubbles (36) at the metal-film interface (64), thereby causing the delamination. The graphene film and support layer form a structure (86) that is collected by a take-up roller (120). The support layer and graphene structure are then separated to obtain the graphene film.
