Description
Technical field
The present invention relates to liquid metal prints field and in particular to one kind carries out liquid on paper surface
The method of metallic print.
Background technology
Liquid metal printing technique is a kind of new electronic circuit manufacture method, can effectively reduce energy
Consumption, cost or even simplification operating procedure etc..However, liquid metal is due to having very high surface
Tension force effect, typically can only just enable smooth printing in some special material surfaces, this
Limit the range of application of liquid metal printing technique to a certain extent.Such as, current liquid
Metallic print is mainly realized on pvc surface, and on more inexpensive printing paper surface not
Can be smoothed out.Reason is that between liquid metal and printing paper does not have the good compatibility.
Research shows, liquid metal is in spherical it is impossible to enough infiltrate printing paper on printing paper surface.This is just
Limit the development further of liquid metal printing technique.
Content of the invention
(1) technical problem to be solved
For liquid metal printing paper surface be in spherical it is impossible to enough infiltration printing paper and cannot be
Paper surface is well on the defect of printing, and the present invention provides one kind to carry out liquid metal on paper surface
The method printing.
(2) technical scheme
Method of the present invention is first printing paper to be carried out spraying, infiltrate pretreatment, then at it
Surface carries out liquid metal printing.
Described be sprayed at 1 atmospheric pressure of room temperature under conditions of carry out, control printing paper surface phase
It is 10%-100% to humidity.
In described spray process, shower nozzle is 1～5cm away from printing paper distance, in order to accurately infiltrate
Need the position printing, shower nozzle must not be too far away apart from the distance of paper；The mistake of paper closely may be led to very much
Sub-dip is moistened, and 1～5cm distance is optimal.
In described spray process, the spouting velocity controlling fog is 0.1～0.3m/s, spray velocity
The too fast planarization that can affect paper；Slowly the relative humidity on paper surface can be led to very much not reach 100%.
In described spray process, water is atomized the ultramicron for 10～50 μm of diameter.10～
50 μm of ultramicron is more beneficial for the absorption of paper.
Described infiltrating time is 1-5s；Preferably 2-4s.Infiltrating time is short to lead to paper surface modification
Unsuccessful；The long deformation that can lead to paper of infiltrating time, effect during 1～5s, especially 2～4s
Most preferably.
After described infiltration operation, the water content of described printing paper is 0.2～1%.
The water absorption rate of described printing paper is 0.2～1%.
In the present invention, described metal be described metal be the alloy of gallium, gallium and indium or bismuth, indium,
Tin alloy.
Process of the present invention it is preferred that comprising the steps:
1) take the printing paper that water absorption rate is 0.2～1%, carry out even spraying on its surface, in spray
During mist, control a diameter of 10-50 μm of steam in fog, the egress rate of fog is
0.1-0.3m/s, away from paper 1-5cm, the relative humidity on printing paper surface is 10%-100% to shower nozzle,
Spraying 1-4s, stops spraying, obtains the printing paper after spraying；
2) by the printing paper standing infiltration 1-5s after described spraying, the water content to printing paper is
0.2-1%；
3) with liquid metal printer, the printing paper surface after standing carries out ga and in mixing gold
Belong to and printing, obtain wire printed product.
(3) beneficial effect
1) the invention provides a kind of simple, low cost is in printing paper printout surface liquid metal
Method.
2) present invention solves the problems, such as that liquid metal, can cannot be in printing paper printout surface
With the infiltration degree by adjusting printing paper, to change the effect of printing；
3) present invention can realize quick, the extensive preparation of printing paper；
4) present invention to experiment condition require not harsh, tap water as inexpensive raw material,
Liquid metal wellability can be effectively improved to complete to test, be that large-scale production provides bar
Part；
5) preparation process of the present invention is simple, easily realizes large-scale production.
