Jet height error compensation method for electrohydrodynamic printing of large-area micro-nano structures

Abstract

The invention discloses a jetting height error compensation method for large-area micro-nano structure electrohydrodynamics printing. The jetting height error compensation method comprises the following steps that (1) the number of constrained points of a base plate is determined; (2) the coordinate value z of the Z axis of the constrained points of the base plate is obtained; (3) a quadrilateral mesh of an XY plane is built; (4) the coordinate value z<j> of the Z axis of the vertex of the quadrilateral mesh of the XY plane is determined; (5) a three-dimensional curved surface of the printing area of the base plate is built; (6) the coordinate value z<c> of the Z axis of the current position of the printing base plate is obtained; and (7) the jetting height of electrohydrodynamics printing is compensated. According to the jetting height error compensation method for large-area micro-nano structure electrohydrodynamics printing, limitation of the existing electrohydrodynamics printing technology to precise forming of a device of a large-area micro-nano structure is broken through, and ink-jet printing of a micro-nano device of a large-area structure and preparation of a device of a micro-nano structure are achieved.

The structural morphology prepared by electrohydrodynamic printing technology will affect the performance of functional devices, such as printing thickness, uniformity, etc. For functional devices with large-area micro-nano structures printed by electrohydrodynamic The change of injection height affects the precise forming of functional devices. However, the existing electrohydrodynamic printing technology does not take an effective method for the change of injection height in the process of large-area micro-nano structure device preparation, which has a great impact Structural morphology of area micro-nano devices, thus affecting their performance

[0005] In summary, the existing electrohydrodynamic printing technology is limited to the preparation of large-area micro-nano structures, and its structural morphology is difficult to be further improved. Therefore, the existing electrohydrodynamic printing technology is difficult to meet the requirements of large-area micro-nano structures. Requirements for Precise Forming of Structural Devices
