Embodiment 1

[0042] The printing device used in this embodiment is as image 3 As shown, it includes a nozzle 1 , an electrode layer 2 , an ink cartridge 3 , a syringe pump 4 , a gas pipe 5 , a gas distribution device 6 , a substrate 7 , a power source 8 , a motorized stage 9 and a computer 10 .

[0043] Among them, the nozzle structure has been specially designed, including such as figure 1 Universal applicators as shown, and as figure 2 The difference of the special nozzle shown is the nozzle array: the general nozzle contains M×N nozzles (1) array, while the nozzle array of the special nozzle has formed the required topology. In both cases, the nozzles are connected to the electrode layer (2), and the corresponding position of each nozzle in the electrode layer is connected to a separate ink cartridge (3), which is filled with ink for inkjet printing. The nozzles adopt the principle of electrodynamic fluid inkjet printing, and are insulated from each other with a distance of d , in...

Embodiment 2

[0051] Applied to the printing of a variety of three-dimensional topological structure graphics arrays, using a general-purpose nozzle, the inkjet of each nozzle can be controlled individually. If the substrate does not move, a single nozzle repeatedly prints on the previous ink dot to obtain a single three-dimensional nanowire. The diameter of the nanowire is the ink dot size. The software program is set to apply voltage to multiple nozzles, and the working nozzle arrays form a specific pattern together, and the required three-dimensional metamaterial array unit is directly printed. Using a special nozzle, the matching three-dimensional metamaterial array graphics unit can be directly printed. Move the substrate and print on another area of ​​the substrate to get another unit. The operation is performed several times to obtain a large-area periodic structure.

Embodiment 3

[0053] Complex graphics unit printing. 1. Nanowires of different sizes: The size of nanowires includes diameter and height (length). Each nozzle can work independently. By adjusting printing parameters, nanowires of different sizes can be obtained. The nozzles of one graphics unit work at the same time, and the size of each nanowire in the array unit can be controlled. 2. Inclined, curved, and helical nanowire arrays: During inkjet printing, move the stage at a fixed speed along one of the x or y axes to obtain nanowires inclined at a certain angle (moving along the positive direction of the x axis, the nanometer The wire tilts towards the negative direction of the x-axis; when moving along the negative direction of the x-axis, the nanowire tilts towards the positive direction of the x-axis; when moving along the positive direction of the y-axis, the nanowire tilts toward the negative direction of the y-axis; when moving along the negative direction of the y-axis, the nanowire...

Abstract

The invention discloses a large-scale ink-jet printing method for a three-dimensional metamaterial array. Through design of a universal sprayer of an M x N nozzle array and a special sprayer of a specific topological structure, pattern information is directly and rapidly printed to a substrate through the nozzle array, and then a large-scale nano structure array can be rapidly and conveniently obtained. Through accurate control over the movement of a displacement table, the size and appearance features of the nano structure can be controlled, and three dimension, inclination, bending, spiral, a heterostructure and the like are included. By utilization of the ink-jet printing method, various complex topological structure arrays can be prepared. The large-scale ink-jet printing method is applicable to various materials and substrates and is widely applied to the demand field of different devices.

Description

technical field [0001] The invention relates to the technical fields of metamaterials, printed electronics, infrared detection, etc., relates to a large-scale preparation method of a complex topological structure array, and in particular to a large-scale inkjet printing method of a three-dimensional metamaterial array. Background technique [0002] Metamaterial is a kind of artificial composite material based on micro-nano structure. Through the topological design of these micro-nano basic units, new characteristics different from the basic structural units are produced, and the propagation of electromagnetic waves can be artificially designed and arbitrarily controlled to realize electromagnetic waves. Spatial gain, beam deflection, polarization rotation, absorption, transparency, etc., which are applied in sensing, display, photovoltaic and other fields. For example, "left-handed materials" with negative permittivity and magnetic permeability that do not exist in nature ca...
