Plasma grafting：
When the group generated by plasma surface activation or plasma-initiated polymerization layer cannot be firmly bonded to the material surface, plasma grafting is often used to improve it. The principle of plasma grafting is as follows: first, the surface activation is used to generate new active groups on the surface of the material, and this group is used to generate chemical covalent bonds with the following active substances, which contain specific groups that can meet the application requirements, so as to achieve the purpose of meeting both surface characteristics and firm binding.
In plasma surface modification of materials, surface grafting by plasma surface processor (PSMP), due to the effect of active particles on surface molecules, the surface molecular chain is fractured to generate new active groups such as free radicals and double bonds, and then surface crosslinking and grafting reactions occur.
