A brush type liquid guiding and infiltrating device

Abstract

A liquid guiding and infiltrating device utilized in an ink brush comprises : a micro-liquid guiding pipe (3) comprising an end portion surrounded at the periphery thereof by a plurality of pen bristles (2) aligned so as to be mutually level. A plurality of protruding pen bristles (1) are arranged at the innermost portion of the mutually level pen bristles (2) and at intervals around the periphery of the micro-liquid guiding pipe (3). A vertical distance from a bristle tip of the mutually level pen bristles (2) to the end portion of the micro-liquid guiding pipe (3) is 4-7 mm. A vertical distance from a bristle tip of the protruding pen bristles (1) to the bristle tip of the mutually level pen bristles (2) is 1-2 mm. The device can uniformly infiltrate a micro-volume of a liquid onto two fibers completely, and can be used to draw on a plane an effective device comprising a super-fine and super-thin film having an arbitrary length. The device is simple in the operating principle and method and easy to implement, and can effectively resolve an issue of infiltration of a micro-volume of a liquid in 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
