(Summary description)Low temperature plasma treatment can effectively purify, activate, coarsene, etch and deposit the surface of the material.   1. Surface cleaning effect of PLASMA treatment: It can effectively remove organic pollutants and oxides from the surface of objects. Main features: wet cleaning method of cleaning, the surface would include residues, and the low temperature plasma surface treatment can achieve high cleanliness of surface, and the low temperature plasma on the surface of nanoscale materials only, will not change the original characteristics of the material, on the surface cleanliness requirements of high technology, is widely used instead of wet process. Treatment mechanism: it mainly relies on the "activation" of the active particles in the plasma to remove the surface stains. The gas is excited into a plasma state. Heavy particles collide with solid surfaces; Electrons react with active groups on the solid surface and break away from the surface as new gaseous substances. Plasma cleaning technology is characterized by both process base material type of object, can be processing, metal, semiconductor, oxides and most of the polymer materials, such as polypropylene, polyester, polyimide, poly (ethyl chloride, epoxy, and even can well with teflon etc, and can realize the overall and partial cleaning and complex structure.   2. Activation effect of PLASMA processing: Three groups -- C=O Carbonyl, -COOH Carboxyl, and −OH Hydroxyl -- are formed on the surface of an object by low temperature plasma treatment. These groups have stable hydrophilic function and have positive effects on bonding and coating. Main features: part can make the polymer surface active atoms, free radicals and unsaturated bond, the reactive group react with active particles in plasma generated new reactive group, thus increasing the surface energy, change the surface chemical properties, enhance the surface adhesion force and cohesive force, tension, including rubber, composite materials, glass, cloth, metal processing, such as involved in all walks of life.   3. Surface roughening and etching effects of PLASMA treatment: Corresponding different materials use the corresponding gas combination to form the gas equivalent ionization body with strong etching property to have chemical reaction and physical impact with the body on the material surface, so that the solid material on the body surface of the material is gasified to form gases such as CO, CO2, H2O, etc., so as to achieve the purpose of micro-etching. Main features: uniform etching, not changing the characteristics of the material matrix; It can effectively roughen the surface of the material and accurately control the amount of micro-corrosion.   4. PLASMA treatment of coating (deposition and grafting) : The plasma treatment process can also be used for micro-coating of materials. Equipped with two corresponding to different gas into plasma reaction chamber at the same time, two kinds of gas in the plasma environment stimulated and aggregation, produces new compounds deposited on the surface of material to form a new coating, using this kind of special effects of plasma treatment, can put the original is not easy to coating materials coated to the surface of the object, such as heart stents, artificial blood vessels to prevent blood clots, coating materials and scratch-resistant surface hydrophobic coating, etc. Main features: It can break the molecular chain on the surface of the material to generate new active groups such as free radicals and double bonds, followed by cross-linking and grafting reactions. The active gas will polymerize on the surface of the material to produce a layer of sediments, so as to achieve the purpose of surface modification. In fact, in the process of low temperature plasma to deal with things, all kinds of positive and negative ions in plasma, high-energy and high speed motion of the electron, the heavy particles can be processed material surface physical and chemical reaction, so the above mentioned four of low temperature plasma surface treatment (or five) are usually produced at the same time.
