Graphene is a new material in which carbon atoms connected by sp² hybridization are tightly stacked into a single layer of two-dimensional honeycomb lattice structure. With excellent optical, electrical, and mechanical properties, graphene holds significant promise for applications in materials science, micro and nano processing, energy, biomedicine, and drug delivery, and is considered a revolutionary material of the future. Chemical vapor deposition (CVD) is one of the most commonly used methods for the controlled production of large-area graphene. Its main principle is to obtain graphene by depositing it on the surface of a metal as substrate and catalyst, and passing a certain amount of carbon source precursor and hydrogen gas in a high temperature environment, which interact with each other. The copper foil for graphene produced by CIVEN METAL has the characteristics of high purity, good stability, uniform wafer and flat surface, which is an ideal substrate material in CVD process.High-precision RA Copper Foil [HTE] High Elongation ED Copper Foil *Note: All the above products can be found in other categories of our website, and customers can choose according to the actual application requirements.
