低温等离子体中粒子的能量一般约为几个至十几电子伏特,大于聚合物材料的结合键能(几个至十几电子伏特),完全可以破裂有机大分子的化学键而形成新键;但远低于高能放射性射线,只涉及材料表面,不影响基体的性能。处于非热力学平衡状态下的低温等离子体中,电子具有较高的能量,可以断裂材料表面分子的化学键, The energy of a particle in a low-temperature plasma is generally about a few to a dozen electron volts, which is larger than the binding energy of the polymer material (a few to a dozen electron volts) and can completely break the chemical bonds of organic macromolecules to form new bonds; however, Much lower than high-energy radioactive rays, involving only the surface of the material, does not affect the performance of the substrate. In the non-thermodynamic equilibrium state of the low-temperature plasma, the electron has a high energy, can break the surface of the chemical bond molecules,
