The introduction of various oxygen-containing groups during plasma treatment makes the surface of the material easy to bond:
With the rapid development of modern industry and science and technology, the requirements for materials are getting higher and higher, which has greatly promoted the progress of material surface modification technology. Among them, plasma surface modification technology has attracted much attention. Plasma is the fourth state of matter. Plasma is a partially ionized gas produced by DC arc discharge, glow discharge, microwave discharge, corona discharge and radio frequency discharge.
Plasma materials are widely used in polymer materials, metal materials, plastic materials, organic materials, polymer materials, biomedical materials, textile materials, etc. Plasma can be used to improve the wear resistance and corrosion resistance of metal materials, thereby increasing the service life and efficiency of metal materials. It can also be used to improve the decoration and smoothness of the material.
A large number of electronic systems with complex functions are used in automotive power control systems. These automotive electronic products require reliable sealing to improve the moisture-proof and anti-corrosion capabilities of components. In these key processes, the plasma surface treatment process can effectively clean and activate the surface of electronic products, improve the bonding force and reliability of subsequent injection molding and glue injection processes, and reduce the occurrence of defects such as delamination and pinholes, thereby ensuring the quality of electronic products. Safe and efficient operation of electronic systems.
Plasma modification of cotton fiber by plasma treatment can improve the spinnability and strength of cotton fiber, improve fiber adhesion and wettability, improve fiber dyeing performance, and perform plasma graft modification and functional finishing. Under proper process conditions, the surface morphology of materials such as PE, PP, PVF2, LDPE, etc., has undergone significant changes in plasma treatment.
Various oxygen-containing groups are introduced during plasma treatment to change the surface properties of the material from non-polar and difficult to stick to a certain polarity, easy to adhere and hydrophilic, which is conducive to bonding, coating and printing. Low-temperature plasma surface modification belongs to the direct reaction of solid and gas. It is a water-free treatment technology. It can greatly save water resources, save energy and environmental protection, reduce the use of chemical solvents and waste disposal. At the same time, the technology has the advantages of fast reaction speed, short action time, and small loss of material physical and mechanical properties, and can obtain a variety of modification effects.
