Abstract

The invention discloses a micro-droplet jetting printing device and a method for preparing a graphene metamaterial microstructure through the device. The micro-droplet jetting printing device and the method are used for solving the technical problem that an existing method for preparing the graphene metamaterial microstructure is complex. According to the technical scheme, the device comprises a nitrogen cylinder, pressure controllers, a liquid accumulator, a piezoelectric micro sprinkler, a microstructure substrate, a three-dimensional associated movement base plate, a three-dimensional associated movement base plate controller, a piezoelectric ceramic driver, a temperature controller and a computer. The method comprises the steps that graphene dispersion liquid is dispersed into picoliter-order uniform graphene micro-droplets through the piezoelectric micro sprinkler, and the liquid droplet diameter and the jetting frequency are adjusted through the piezoelectric ceramic driver; and then the three-dimensional associated movement base plate is controlled through the computer, the accumulation track of the graphene micro-droplets on the substrate is controlled, the graphene microstructure is obtained through point-by-point, line-by-line and layer-by-layer accumulation, meanwhile, the temperature controller is utilized for controlling the evaporation rate and solute migration in the graphene micro-droplet deposition process, and complex graphene metamaterial microstructure patterns are obtained. The method is simple and practicable.

Description

technical field [0001] The invention relates to a droplet jet printing device, and also relates to a method for preparing graphene supermaterial microstructures by using the droplet jet printing device. Background technique [0002] Graphene is a new carbonaceous material that is densely packed into a two-dimensional honeycomb lattice structure by a single layer of carbon atoms. Since Novoselov and Geim prepared graphene that exists at room temperature by micromechanical exfoliation in 2004, it has rapidly set off a global trend. The upsurge of graphene research. Graphene is by far the thinnest and lightest material with the highest strength, the best electrical conductivity, and the best thermal conductivity, so it has been widely used in the fields of chemistry, physics, biology, machinery, medicine and even tissue engineering. In particular, graphene has great development prospects in the field of electromagnetic metamaterials, especially terahertz metamaterials, due to ...
