Abstract:
1. A method for producing a substrate coated with multi-layer graphenes, comprising laminating, on surface of a substrate, multi-layer graphenes from a mass of multi-layer graphenes, wherein the mass of multi-layer graphenes is an aggregation having a three-dimensional shape of many discrete multi-layer graphenes, approximately radially or approximately vertically to a plane or spherical surface in a three-dimensional space without being laminated to each other, and the thicknesses of the multi-layer graphenes are in the range of 0.34 nm to 100 nm; and wherein the mass of multi-layer graphenes is produced by a method comprising: preparing a powdery and/or particulate material of an organic compound pre-baked at a temperature of 1000° C. or lower, to an extent of containing remaining hydrogen; charging the powdery and/or particulate material in a closed vessel made of a heat-resistant material; and subjecting the powdery and/or particulate material together with the vessel to hot isostatic pressing treatment using a compressed gas atmosphere, wherein a maximum temperature in the hot isostatic pressing treatment is 900° C. to 2000° C., and the maximum temperature in the hot isostatic pressing treatment is higher than the pre-baking temperature.
