Research Status on Surface Modification of Materials by Low-Temperature Plasma

As a new type of method to activate molecular, low-temperature plasma has a large number of active particles with various types, which are easy to react with the surface of the material, and is suitable for surface modification treatment of the materials.The main discharge methods of low-temperature plasma suitable for surface modification of materials, the principle and application range of low-temperature plasma generated by each discharge method were reviewed.Then, the effects of low-temperature plasma on the surface microstructure and properties of the material after modifying the material surface, including the surface chemical elements, wettability, and surface microstructure were summarized.Finally, the existing problems and future development direction of low-temperature plasma for material surface modification were pointed out.
