The feasibility of using the selective adsorption principle to realize the automatic forming of nano-patterns, and the effect of the transfer mode on the automatic forming effect were studied. The heating process of bulk aluminum and two nano-aluminum clusters was studied by molecular dynamics method respectively, the potential energy-temperature curve of nano-aluminum liquid was obtained, and the simulation temperature for automatic forming of nano-aluminum liquid pattern was determined; the LAMMPS software was used to establish the printing plate model required for automatic pattern forming; the wetting and spreading of nano aluminum liquid on the surface of graphene-copper-based printing plate were studied by means of liquid film transfer printing and droplet spray printing respectively. Nano-aluminum liquid can realize automatic pattern forming on the surface of graphene-copper-based printing plate; the effect of automatic pattern forming is different between liquid film model and droplet model. When the liquid film is thin (double-layer aluminum atoms) and the simulation time is 1,200 ps, the whole system reaches a dynamic equilibrium, the thickness of aluminum liquid in the pattern area is about 1.8 nm, and the effect of automatic pattern forming is good; when the liquid film is thick (three layers of aluminum atoms) and the simulation time is 1,200 ps, the whole system reaches dynamic equilibrium, but there are more aluminum atoms left between the two lines in the pattern area and the automatic forming effect is poor. The two droplet models both achieve better pattern forming effect. When the number of droplets is 4, the pattern with uniform thickness can be formed when the simulation time is 3,000 ps, and when the number of droplets is 6, the pattern area can form stable and uniform lines when the simulation runs 600 ps. Using the principle of selective adsorption principle can realize the automatic forming of nano pattern, and the forming effect is greatly affected by the transfer modes of aluminum liquid. If it is applied in practice, the influence of forming effect and printing process should be comprehensively considered.
