Gilding with Graphene: Rapid Chemical Vapor Deposition Synthesis of Graphene on Thin Metal Leaves
Abstract
Gilding is the ancient process of coating intricate artifacts with precious metals. Fascinating Egyptian and Chinese sculptures, coated with −1). Mathematical models of growth kinetics guide the development of extremely rapid synthesis conditions, resulting in the formation of high‐quality graphene on Pd in less than a minute, owing to the graphene grains growing twice as fast as copper‐catalyzed growth. The graphene monolayer on the leaf increases the effective surface modulus by 59% to 236 GPa. Uniaxial strain testing with Raman spectroscopy reveals the excellent crystallinity of graphene by probing the stress‐induced phonon shifts. This new material could open exciting opportunities in utilizing high‐quality 2D materials to coat large structures.
