Graphene and graphite are of great interest in materials science. Using chemical vapor deposition at various CH₄:H₂ 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 10⁶ to 0.2 Ω □⁻¹, and nearly equaled the values of highly orientated pyrolytic graphite and glassy carbon. The graphene-laminated materials featured a range of transmittance, reflectance, and electrical conductance properties.

通过化学气相沉积获得的石墨烯层压结构：从石墨烯到石墨

石墨烯和石墨在材料科学中非常重要。通过以各种CH ₄：H ₂比率进行化学气相沉积，我们合成了具有石墨烯层压结构的材料，范围从石墨烯到石墨。较低比例的CH ₄和较低的合成温度产生较少的石墨烯层。随着石墨烯层数的增加，透明性从透明变为半透明，黑色和银色。薄层电阻率为10 ⁶到0.2Ω□ ^-1，几乎等于高度取向的热解石墨和玻璃碳的值。石墨烯层压材料具有一系列透射率，反射率和电导率特性。
