Abstract

The invention discloses an acoustophoretic composite flow focusing micro-nano jet printing device. The device comprises an inner nozzle communicated with a jet printing liquid supply device, a flow focusing assembly and an acoustophoresis focusing assembly, wherein the flow focusing assembly and the acoustophoresis focusing assembly are distributed outside the inner nozzle, the inner nozzle is provided with a liquid outlet, and a substrate bearing jet printing liquid drops is arranged under the liquid outlet. According to the micro-nano jet printing method using the micro-nano jet printing device, the jet printing liquid is subjected to flow focusing and acoustophoresis focusing in sequence, the jet printing liquid can be broken into micron-sized micro-droplets through flow focusing, the liquid droplets are further broken through acoustophoresis focusing, the liquid droplet breaking process becomes controllable to obtain nano-level droplets. According to the invention, controllable micron-scale even nano-scale microdroplet preparation is achieved, dependence of an existing electronic jet printing technology on electric, chemical and magnetic characteristics of a material is eliminated, possibility is provided for lossless jet printing of high-viscosity printing ink, high-precision and high-resolution printing of the high-viscosity jet printing material is achieved, and the large-area and high-precision cross-scale manufacturing requirements of printed electronic devices are met.
