Writing brush type liquid guide infiltration device

Abstract

The invention relates to the field of micro-liquid infiltration devices, in particular to a writing brush type liquid guide infiltration device. The writing brush type liquid guide infiltration devicecomprises a micro-liquid guide pipe (3), wherein the periphery of the head part of one end of the micro-liquid guide pipe (3) is wrapped with a bundle of flush pen bristles (2), and a plurality of protruding pen bristles (1) are arranged on the innermost side of the flush pen bristles (2) along the periphery of the micro-liquid guide pipe at equal intervals; the vertical distance between the tipsof the flush pen bristles (2) and the head part of the micro-liquid guide pipe is 4-7 mm; the vertical distance between the tips of the protruding pen bristles (1) and the tips of the flush pen bristles (2) is 1-2 mm. By means of the device, micro-liquid can evenly infiltrate two fiber bristles, and an ultra-thin film with any length can be drawn on a plane. A method is simple in principle, easyto implement and capable of effectively solving the micro-liquid infiltration problem of a micro-liquid supply system.

Description

technical field [0001] The invention relates to the field of trace liquid infiltration devices, in particular to a writing brush type liquid guide and infiltration device. Background technique [0002] One-dimensional patterns such as micron wires prepared by functional organic and inorganic phase materials have been widely used in integrated optoelectronic devices, biosensors and biodetection in general fields. The performance of these detection devices largely relies on patterned functional materials. Inspired by the transfer control of brush ink in traditional Chinese painting, various functional liquid-phase materials, such as suspensions of quantum dots, small molecules, polymers, and nanoparticles, can be directly written on substrates with well-preserved physicochemical properties . Therefore, this biomimetic direct writing technology is of great significance in the preparation of functionalized micropatterns and integrated functional devices. [0003] Yet traditio...

AI Technical Summary

Problems solved by technology

[0003] Yet traditional writing brush has many defects: (1) writing brush is dipped in ink and writes and draws, and it cannot draw lines indefinitely, and no matter how much ink is dipped in, the lines it draws all begin to be thick, and the more Later, it became lighter, which caused the prepared film layer to be thicker at first, and then thinner, which could not meet the requirements of practical applications.

(2) It is difficult to draw a film with a width of <1mm with a traditional brush, which is difficult to meet the needs of micropatterns and integrated functional devices
