Graphene-enabled block copolymer lithography transfer to arbitrary surfaces
Abstract:
A method of graphene-enabled block copolymer lithography transfer to an arbitrary substrate comprising the steps of applying graphene on a surface, adding block copolymers to the graphene on the surface, phase-separating the block copolymers, forming nanopatterned phase separated block copolymers, delaminating the graphene, and transferring the graphene and nanopatterned phase separated block copolymers to a second surface. A layer of nanopatterned phase separated block copolymers on an arbitrary surface comprising a first arbitrary substrate absent of chemical preparation, a layer of graphene on the first arbitrary substrate, and a layer of phase-separated block copolymers on the layer of graphene, wherein the layer of phase-separated block copolymers on the layer of graphene was formed on a second substrate and delaminated via water liftoff and wherein the nanopatterned phase separated block copolymers are utilized as a shadow mask for lithography on the first arbitrary substrate.
