Abstract

The invention relates to a method for printing liquid metal on a paper surface. The method comprises the following steps: performing mist spraying and infiltration pretreatment on printing paper at first, and then printing the liquid metal on the surface of the treated printing paper. By adoption of the method provided by the invention, the problem that the liquid metal cannot be printed on the surface of the printing paper is solved; the printing effect can be changed by adjusting the infiltration degree of the printing paper; and meanwhile, the requirement of the method for experimental conditions is not strict, that is, tap water can be adopted as a low-cost raw material, so that the infiltration property of the liquid metal can be effectively improved for experimental completion, and favorable conditions are provide for the large-scale production.

Example Embodiment

[0030] Example 1

[0031] This embodiment relates to a method for liquid metal printing on paper, including the following steps:

[0032] 1) Take A4 printing paper and use a single spray nozzle to spray evenly on its surface. During the spraying process, control the diameter of the water vapor in the mist to 10-50μm, the mist outlet velocity to 0.1-0.3m/s, and the nozzle distance The paper surface is 1-5cm, the relative humidity of the printing paper surface is 100%, spray for 1-4s, stop spraying, get the sprayed printing paper;

[0033] 2) The sprayed printing paper is allowed to stand and soak for 1-4 seconds until the water content of the printing paper is 0.2-1%;

[0034] 3) Use a liquid metal printer to perform Ga liquid metal printing on the stationary printing paper surface to obtain a linear printed product. The printing pen and the printing paper touch each other during printing.

[0035] The scanning electron microscope image of the product structure obtained when the infiltration time is 2s in this embodiment is as follows figure 2 , The schematic diagram of the printing process is as figure 1 a

[0037] This embodiment relates to a method for liquid metal printing on paper, including the following steps:

[0038] 1) Take A4 printing paper and spray uniformly on its surface with multi-spray nozzles. During the spraying process, control the diameter of the water vapor in the mist to 10-50μm, the outlet velocity of the mist is 0.1-0.3m/s, and the nozzle distance Paper surface 1-5cm, relative humidity of the printing paper surface is 10%, spray for 1-4s, stop spraying, get sprayed printing paper;

[0039] 2) The sprayed printing paper is allowed to stand and soak for 1-4 seconds until the water content of the printing paper is 0.2-1%;

[0040] 3) Use a liquid metal printer to perform Ga on the surface of the printing paper after standing. 75.5 In 24.5 Metal printing, linear printing products. The printing pen and the printing paper touch each other during printing.

[0041] The schematic diagram of the printing process in this embodiment is as follows figure 1 b)

[0042] Example 3

[0043] This embodiment relates to a method for liquid metal printing on paper, including the following steps:

[0044] 1) Take A4 printing paper and spray uniformly on its surface with a sleeve spray nozzle. During the spraying process, control the diameter of the water vapor in the mist to be 10-50μm, the mist outlet rate is 0.1-0.3m/s, and the nozzle distance The paper surface is 1cm, the relative humidity of the printing paper surface is 100%, spray for 1s, stop spraying, get the sprayed printing paper;

[0045] 2) The sprayed printing paper is allowed to stand and soak for 1 second until the water content of the printing paper is 0.2%;

[0046] 3) Use a liquid metal printer to perform Ga on the surface of the printing paper after standing. 75.5 In 24.5 Metal printing, get liquid metal wire printing products. The printing pen and the printing paper touch each other during printing.

[0047] The schematic diagram of the printing process in this embodiment is as follows figure 1 c1), the structure of sleeve and printing nib is as figure 1 c2).
