Abstract:
1. A method for synthesizing carbon nanomaterials, comprising: preparing a substrate set where at least one layer of close packed particles which act as dummy matrixes is placed on a substrate; depositing carbon nanomaterials on the substrate using a CVD method, by inducing a gas chemistry for carbon nanomaterials in a space between the dummy matrixes and the top surface of the substrate; and recovering the substrate, on which the carbon nanomaterials are deposited, by removing the dummy matrixes from the substrate set, wherein a diamond film is coated onto the upper surface of the dummy matrixes in contact with a carbon-containing gas activated by plasma or heat, and the diamond film isolates the space from the plasma or the heat thus to induce the gas chemistry for carbon nanomaterials.
