Description

technical field [0001] The invention relates to the technical field of making electrojet 3D printer nozzles, in particular to a method for preparing nanoscale electrojet 3D printing nozzles by using swelling technology. Background technique [0002] Electrojet printing is based on the theory of electrohydrodynamics. Under the comprehensive action of electric field force, gravity, surface tension, etc., the liquid forms a stable and fine jet at the outlet of the needle, which is much smaller than the inner diameter of the needle. Patterning of functional materials on the substrate. Due to the advantages of high printing accuracy, wide ink adaptability, strong controllability of printing droplets, and low substrate requirements, electrojet printing has been widely used in electronic transistors, memristors, micro-nano sensors, biomaterials and structures in recent years. It has demonstrated its outstanding advantages and has been paid attention to by researchers from all over...
