Abstract

The invention discloses a carbon fiber monofilament microplasma surface micro-area processing device and a using method. The carbon fiber monofilament microplasma surface micro-area processing devicecomprises a first microplasma generation assembly, a second microplasma generation assembly and a fixing assembly, wherein the first microplasma generation assembly generates a first microplasma jet flow and jets the first microplasma jet flow to the surface of a carbon fiber monofilament fixed on the fixing assembly; and the second microplasma generation assembly generates a second microplasma jet flow and jets the second microplasma jet flow to the surface of the carbon fiber monofilament fixed on the fixing assembly. The carbon fiber monofilament microplasma surface micro-area processing device can perform accurate and controllable micro-area processing on the surface of the carbon fiber monofilament by utilizing the generated microplasma jet flows in an atmospheric environment and under a mask-free condition, and is simple in process, convenient to operate and low in cost; and meanwhile, multiple processing processes can be synchronously performed, for example, the surface of the carbon fiber monofilament is etched and nanoparticles are deposited at the same time, so that the processing means of the surface of the carbon fiber monofilament is enriched, and the processing efficiency is greatly improved.

Description

Technical field [0001] The invention relates to the technical field of carbon fiber surface processing, in particular to a carbon fiber monofilament microplasma surface micro area processing device and a use method. Background technique [0002] Carbon fiber refers to a microcrystalline graphite material with a carbon content of more than 95%. It has a series of excellent properties such as high modulus, high strength, low density, and corrosion resistance. It has a wide range of applications in aerospace, electronic products, medical equipment and other fields. . Carbon fiber monofilaments are carbon fiber tows with a diameter of 5-7 microns. Because of their small cross-sectional size, good biocompatibility, and good electrochemical properties, they are often used to make microelectrodes. At present, carbon fiber microelectrodes have a wide range of applications in the fields of electrochemical analysis, cell biology, immunology, and in vivo detection. [0003] However, due to ...
