A double-row fiber-like array pen and its manufacturing method

Abstract

The invention discloses a double-row type fiber array broad brush. The broad brush comprises two pieces of metal foil, wherein a plurality of comb teeth which extend downwards and are evenly spaced are arranged at the lower end of each piece of metal foil, a hollowed-out groove extending upwards from the root is formed between every two adjacent comb teeth, a hollowed-out groove extending upwards from the root is also formed in the outer side of each comb tooth on the outmost side, and the two pieces of metal foil are arranged in a cross manner, so that the comb teeth on the metal foil are arranged in a spaced and cross manner. A uniform nano film layer can be brushed by the aid of the broad brush. The invention further discloses a producing method of the double-row type fiber array broad brush.

Description

technical field [0001] The invention relates to a double-row fiber array row pen made of metal foil and a manufacturing method thereof. Background technique [0002] Organic optoelectronic materials have the advantages of controllable performance and easy processing, which present attractive application prospects in the fields of electronics, optical communication, information storage, and life sciences. At present, most of the methods for preparing organic photoelectric materials are obtained by spin coating, dip coating, ink jet printing and screen printing. In order to develop a solution processing technology at room temperature to carry out research on optoelectronic functional nanomaterials with precise positioning and complex micro / nano structures, Jiang Lei’s research group at the Institute of Physics and Chemistry of the Chinese Academy of Sciences was inspired by the directional delivery of liquid droplets by using one-dimensional anisotropic structural fibers in Ch...

AI Technical Summary

Problems solved by technology

However, these previous research works were all done in the laboratory, and the prepared fiber array structure currently has the following problems: (1) The fiber array used is handmade, which is limited by the individual differences of operators; (2) The single row of animal hair The ordinary row of pens can be made arbitrarily, but it is impossible to do it by hand if it is made into micron-level intervals and nano-level tips; (3) use composite materials and abrasive tools to reproduce When the pen is single-piece, the mechanical strength of the tip of the hair cannot meet the requirements of brushing film; (4) drawn with synthetic fibers, the consistency of the two hairs can basically achieve batch consistency

However, there are no examples of mechanized production of multi-haired products, both at home and abroad.
