Problems solved by technology
[0004] The morphology of the microstructure array often has an important impact on its function. If the morphology characteristics of the microstructure can be precisely controlled, it will be of great help to improve its performance. Therefore, it is very important to control the morphology of the microstructure. The parameters during printing control the morphology of the microstructure that is printed, and this control method has a low precision in controlling the morphology of the microstructure

The invention discloses a method for regulating and controlling the morphology of electrofluidic jet printing microstructures. The contact angle between the printed line and the substrate and the thickness distribution of the intersection of the printed line array are compared with the target value, and the electric field regulation signal is applied according to the comparison result, thereby implementing the regulation of the line shape and the shape of the intersection point of the line array; The microstructure is formed by spraying droplets in a grid surrounded by a linear array in the electroatomization mode, detecting the thickness and shape of the microstructure, comparing it with the target value, and applying an electric field regulation signal according to the comparison result, thereby implementing the microstructure adjustment. shape control. The present invention also provides a system and apparatus for implementing the above method. The invention adopts the combination of electrospinning and electrospray technology to manufacture the microstructure, and uses an additional electric field to control the morphology, thereby greatly improving the manufacturing efficiency and the morphology precision of the microstructure.
Description
technical field [0001] The invention belongs to the technical field of electrofluidic inkjet printing manufacturing, and more particularly, relates to a method and a device for regulating the morphology of electrofluidic inkjet printing microstructures. Background technique [0002] Microstructure array refers to the arrangement of micro-nano structures with a certain shape in a certain way. The micro-structure has excellent performance in the surface hydrophobicity and surface modification of the product, so it is widely used in medical, MEMS, optics, architecture. , transportation and other fields. [0003] Electrofluidic printing technology is a high-resolution printing technology, which can eject droplets much smaller than the size of its nozzle, and has broad prospects in the field of micro-nano manufacturing. At present, microstructure arrays are usually manufactured by photolithography, thermal reflow, soft imprinting, etc., all of which require heating or complex pr...
