(Summary description)The low temperature plasma surface treatment system technology provides a means of microscopic modification of environmentally friendly and low-cost materials without the need for mechanical processing and chemical reagents. Low temperature plasma surface technology can not only clean, activate and etch materials, but also optimize the surface of plastic, metal or ceramic materials, improve their bonding ability or give new surface characteristics. Its potential medical value includes improving the surface hydrophilicity or hydrophobicity of the material, reducing surface friction, and improving the surface barrier of the material.   Low temperature plasma surface treatment is a technique that can improve the adsorption capacity of polymer surface by changing only a few atomic layers. The modified polyolefin, silica gel and fluoropolymer have good adhesive properties. By using low temperature plasma technology, we can obtain the required material surface without losing the physical properties of the material itself. Plasma treatment will not affect the physical properties of the material, the material parts treated by plasma compared with the parts not treated by plasma, is generally difficult to distinguish visually, physically.   Low temperature plasma surface treatment is usually a plasma reaction process that causes changes in molecular structure or atomic arrangement on the surface. Plasma surface treatment can produce highly active groups at low temperature even in inert environment such as oxygen and nitrogen. In the process, the plasma also produces high-energy ultraviolet light, which, along with the rapidly producing ions and electrons, provides the energy needed to break the polymer bonds and produce surface chemical reactions. In this chemical process, only a few atomic layers on the surface of the material are involved, and the bulk properties of the polymer remain unchanged. The selection of appropriate reaction gas and process parameters can promote some specific reactions, resulting in the formation of special polymer attachments and structures. Reactants can be selected to cause the plasma to react with the substrate to form volatile attachments. The treated appendages on the surface of the material can be removed by vacuum pump without further cleaning or neutralization, and such functions as surface cleaning modification and etching can be realized.
