Embodiment 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 be 10-50μm, the outlet velocity of the mist to be 0.1-0.3m / s, and the distance between the nozzles The paper surface is 1-5cm, the relative humidity of the printing paper surface is 100%, spray for 1-4s, stop spraying, and get the sprayed printing paper;

[0033] 2) standing and soaking the sprayed printing paper for 1-4s 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 surface of the printing paper after standing to obtain a linear printed product. During the printing process, the printing pen and the printing paper are in contact with each other.

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.

Description

technical field [0001] The invention relates to the field of liquid metal printing, in particular to a method for liquid metal printing on the surface of paper. Background technique [0002] Liquid metal printing technology is a new method of manufacturing electronic circuits, which can effectively reduce energy consumption, cost and even simplify the operation process. However, due to the high surface tension of liquid metal, smooth printing can only be achieved on the surface of some special materials, which limits the application range of liquid metal printing technology to a certain extent. For example, the current liquid metal printing is mainly realized on the surface of PVC, but it cannot be carried out smoothly on the surface of lower-cost printing paper. The reason is that there is no good compatibility between liquid metal and printing paper. Studies have shown that the liquid metal is spherical on the surface of the printing paper and cannot infiltrate the print...
