(Summary description) Since the 21st century, with the rapid development of science and technology and modern industry, new materials of various functions have emerged to meet the development needs of various industries. At the same time, this has also led to the development and advancement of various surface modification technologies. Plasma surface modification refers to the activation modification by exposing the material to a non-polymerized gas plasma and bombarding the material surface with plasma to cause changes in the material surface structure. Generally, the surface modification of the functional layer is very thin (a few nanometers to hundreds of nanometers) and does not affect the overall performance of the material; after modification, the material surface can be hydrophilic, anti-abrasive, decorative, coloring, printing, adhesive, antistatic, etc.        Now plasma technology for fiber surface modification is also widely noted. Plasma treatment of carbon fiber surface can improve the adhesion and ensure that the fiber tensile strength does not decrease. In addition, plasma treatment can also eliminate surface micro-cracks of carbon fibers, reduce stress concentration and improve the tensile strength of the fibers themselves. Plasma treatment of Kevlar fiber, aramid fiber is also effective. PET fiber is widely used, but the dyeing, moisture absorption, anti-fouling properties are poor, after plasma treatment, the introduction of polar groups on the surface, the generation of free radicals, cross-linking layer, effectively improve a variety of properties.        Electronic components, automotive parts and other industrial components in the production process due to cross contamination, natural oxidation, solder, etc., the surface will form a variety of dirt, these pollutants will affect the quality of the components in the subsequent production of welding, bonding and other related processes, reducing the reliability of the finished product and pass rate. Plasma treatment treats the surface of the workpiece by chemical or physical action, and the reaction gas ionizes to produce highly reactive reaction ions that react chemically with the surface contaminants for cleaning. The choice of reaction gas needs to be based on the chemical composition of the contaminant. Chemical reaction-based plasma cleaning speed, good selectivity, better cleaning effect on organic pollutants. Surface reaction to the physical role of the main plasma cleaning is very commonly used is the use of argon, will not produce oxidation by-products, etching effect isotropic. In general the plasma surface modification process, the chemical reaction and physical action is co-existing, resulting in a better selectivity, uniformity and directionality.        Due to the development direction of precision and miniaturization in the industrial field, plasma surface modification technology with its fine and clean, non-destructive modification advantages in the semiconductor industry, chip industry, aerospace and other high-tech industries will also have increasingly important application value.
