▎ 摘　　要

NOVELTY - The method involves growing pristine monolayer or few-layer continuous graphene on a catalytic film to form a graphene/catalytic film bilayer. A layer of material is removed on top of the graphene surface in a predetermined pattern by printing on the surface of the graphene surface with a laser printer and selectively depositing a liquid binding material in a powder-bed layer of a 3D printer. The graphene is released from the catalytic film such that the graphene is in a form of the patterned layer. A released graphene and the patterned layer are attached to a flexible polymer substrate. USE - Method for forming a workpiece of an electronic device. Uses include but are not limited to flexible/foldable electronics, wearable vapor sensors for environmental monitoring, printable biosensors for facile medical diagnosis and inexpensive next- generation energy materials e.g. supercapacitors and transparent electrodes. ADVANTAGE - The method enables transfer of the graphene from growth substrates to other surfaces in an efficient manner. The method enables releasing the graphene from the catalytic film such that the layer of material is sufficiently rigid that resists folding or tearing through rest of process, thus ensuring that the graphene film preserves its very high electronic and structural quality. DETAILED DESCRIPTION - The substrate is made of glass, silicon, silicon dioxide, aluminum oxide, sapphire, germanium, gallium arsenide, indium phosphide, an alloy of silicon and germanium, PET, polyimide and silk. An INDEPENDENT CLAIM is also included for a workpiece. DESCRIPTION OF DRAWING(S) - The drawing shows a cross-sectional view of an electronic device comprising a workpiece.
