Problems solved by technology

Dielectric barrier discharge, as one of the low-temperature plasma treatment methods, has simple treatment conditions and is easy to obtain a large amount of high-energy-density plasma, so it has a broad application market. However, this method is in the form of filament streamer discharge under atmospheric pressure, which cannot Uniform treatment on the surface of the material may easily cause burns or perforations on the surface of the material, which limits its application prospects

Abstract

The invention relates to a surface modification method of an insulated woven material, and belongs to the technical field of surface modification. The method comprises the following steps: putting a cathode material and an anode material into an electrolyte solution, applying 100 to 400V voltage between a cathode and an anode, and forming a uniform and stable cathode plasma arc region at the cathode; ensuring that an insulated woven material continuously penetrates through the cathode plasma arc region, so as to realize surface modification treatment on the insulated woven material. The methodadopts a liquid-phase plasma electrolysis technology, realizes large-area continuous surface treatment on the insulated woven material, achieves the effect of cleaning, and deposits a coating on thesurface of the material, so as to improve the mechanical property of the material. The method is simple to operate, low in cost, high in efficiency, not limited by the size and shape of the material,and good in coating uniformity, provides a new thought for surface treatment on the insulated woven material, can realizes large-area continuous surface treatment on the insulated woven material, andis easy to realize industrialization.
