Method for printing liquid metal on paper surface

[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.

[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)

[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.
