Abstract

The invention provides a glow plasma generating device for surface modification of a polymer material, including: a high frequency and high voltage power supply, a high voltage electrode, an insulating medium, a metal mesh electrode and a modified material, wherein the high voltage electrode is connected to the high voltage and high frequency power supply through the lead wire, the metal mesh electrode is connected to the ground terminal through the lead wire, the insulating medium is disposed between the high voltage electrode and the metal mesh electrode, the modified material is placed on the surface of the metal mesh electrode; the high voltage electrode and the insulating medium, the insulating medium and the metal mesh electrode, and the metal mesh electrode and the modified materialall keep in sealed contact; and when the voltage applied by the high voltage and high frequency power supply reaches the discharge voltage, the glow discharge plasma is generated in the discharge region and acts on the modified material. The invention suppresses the development degree of the electron collapse by constructing a sub-millimeter discharge gap by directly contacting the modified material with the electrode, which further suppresses the generation of the filament discharge, and is beneficial to improving the effect of the plasma on the surface modification of the material.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a glow plasma generating device for surface modification of polymer materials. Background technique [0002] Polymer material is a general term for plastic, rubber and fiber. In recent years, polymer materials have been widely used due to their obvious advantages such as low density, low specific strength and specific modulus compared with metals, low cost, simple processing technology, and good chemical and thermal stability. Used in construction, medical treatment, printing, agriculture, military, aerospace, composite materials and other related fields, it has become an indispensable and important material in national economic construction and daily life. However, for common polymer materials, due to their special molecular structure, the crystallinity of the material is high and the surface energy is low, resulting in its hydrophilicity, adhesion, shrinkage resistan...
