The present invention relates to a kind of method that knife coating prepares carbon-base film material, this method includes：Finely dispersed slurry is scratched in the substrate of different surfaces structure using knife coating as substrate with metals such as Copper Foil, aluminium foil, titanium foils as substrate or so that PET, cotton, sand paper etc. are nonmetallic, and be dried to obtain carbon-base film material under certain condition；By selecting regulation and control substrate surface pattern, the carbon-base film material combined closely with substrate and the self-supporting carbon-base film material that can be peeled off with substrate can be obtained.It is preparation process is simple of the present invention, strong to the designability of thin film, the carbon-base film material of different morphologies feature and performance can be obtained by the selection to different base and the regulation and control of substrate surface pattern. |
