▎ 摘 要
Graphene and graphite are of great interest in materials science. Using chemical vapor deposition at various CH4:H-2 ratios, we synthesized materials with graphene-laminated architectures, ranging from graphene to graphite. A lower proportion of CH4 and lower synthesis temperature produced fewer graphene layers. The transparent properties changed from transparent to semi-transparent, black, and silver as the number of graphene layers was increased. The sheet electrical resistivity ranged from 10(6) to 0.2 Omega rectangle(-1), and the smaller resistivity was nearly equaled as the values of highly orientated pyrolytic graphite and glassy carbon. The graphene-laminated materials featured a wide range of transmittance, reflectance, and electrical conductance properties. (C) 2017 Elsevier B.V. All rights reserved.
