Preparation method of multi-element nano material directionally coated graphite paper with high dispersion

The invention discloses a preparation method of graphite paper directionally coated with a multi-element nano material with high dispersion, and belongs to the field of nano material modification. The preparation method comprises the following steps: (1) placing functional nano materials such as carbon nano tubes and graphene at a cathode of a high-voltage driving circuit; (2) taking graphite paper with a certain size, and fixing the graphite paper at the anode of the high-voltage driving circuit by using an electrode clamp; (3) a power supply is switched on, a gap between the two electrode plates is electrically broken down to generate an electric arc, and the carbon nanomaterial between the two plates is heated to expand to form a state similar to aerosol; and (4) under the coupling action of a plurality of force fields such as heat, electricity and the like, the nano material is directionally coated on the surface of the graphite paper. The method disclosed by the invention is simple in equipment and good
