▎ 摘　　要

NOVELTY - Graphene functionalization that preserves electronic properties and enables nanoparticles deposition, involves providing graphene; and functionalizing the graphene via non-covalent functionalization. Functionalizing the graphene via non-covalent functionalization involves providing one from 1-hydroxypyrene solution, 1-pyrenecarboxylic acid dissolved in methanol, and 4-aminomethyl pyridine; incubating the graphene; rinsing the graphene; drying the graphene; and forming functionalized graphene. The functionalized graphene preserves electronic properties and enables nanoparticles deposition. USE - The method is useful for graphene functionalization that preserves electronic properties and enables nanoparticles deposition (claimed). ADVANTAGE - The method can help in the development of quantum Hall resistance standards based on graphene technology and can provide a platform for other graphene devices such as sensors with superior electronic properties compared to other functionalization methods. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a functionalized graphene where the graphene functionalization preserves electronic properties and enables nanoparticles deposition formed from the method above; or a functionalized graphene where the graphene functionalization preserves electronic properties and enables nanoparticles deposition formed from the process involving providing graphene; functionalizing the graphene via covalent functionalization where the step of functionalizing the graphene via covalent functionalization comprises the steps of providing one from N-ethylamino-4-azidotetrafluorobenzoate (TFPA-NH2) in methanol and phosporine-ethylamino-4-azidotetrafluorobenzoate (TFPA-PO3) in methanol; and incubating the graphene; rinsing the graphene; drying the graphene; and forming functionalized graphene where the functionalized graphene preserves electronic properties and enables nanoparticles deposition.
