Introduction: The energy of particles in low-temperature plasma is generally about several to ten electron volts, which is greater than the binding energy of the polymer material (several to several dozen electron volts), and can completely break the chemical bonds of organic macromolecules to form new bonds; Far lower than high-energy radioactive rays, it only involves the surface of the material and does not affect the performance of the matrix. In a low-temperature plasma in a non-thermodynamic equilibrium state, the electrons have higher energy and can break the chemical bonds of the molecules on the surface of the material, increasing the chemical reactivity of the particles (greater than thermal plasma), and the temperature of neutral particles is close to room temperature. The advantages provide suitable conditions for the surface modification of heat-sensitive macromolecular polymers. By low-temperature plasma surface treatment, a variety of physical and chemical changes occur on the surface of the material, or rough etching occurs, or a dense cross-linked layer is formed, or oxygen-containing polar groups are introduced to make hydrophilicity and adhesion. , Dyeability, biocompatibility, and electrical properties were improved. Treatment of the surface of the material under appropriate process conditions results in a significant change in the surface morphology of the material. A variety of oxygen-containing groups are introduced to change the surface from non-polar, hard-to-adhesive to a certain polarity, easily viscous, and hydrophilic. Sex, is conducive to bonding, coating and printing. Electromagnetic high-frequency high voltage is applied across the electrodes to generate gas arc discharge between the two electrodes to form a plasma region. The electrons continuously collide with gas molecules during the movement, resulting in a large number of new electrons. When these electrons reach the anode, they will accumulate on the surface of the medium and modify the surface.
