Problems solved by technology

[0004] Therefore, the existing method for surface treatment uses low energy, which is not enough to break the surface bonds, and the corona discharge current is too small, so the treatment cost, efficiency and effect are relatively limited, especially for some special polymers, such as PI, Treatment effects such as LCP, MPI, PET and PTFE are limited, because the surface energy of these polymers is very low, the surface is very inert, and high-energy ions are often required to chemically break bonds, and the particle energy during corona treatment is only a few eV, which is not enough to increase its surface energy, so that it cannot increase the bonding strength of polymers to metals or non-metals

Abstract

The invention provides a surface treatment method for a 5G polymer, and belongs to the technical field of polymer surface treatment. A polymer is subjected to oxygen element injection and addition, polymer matrix elements and injected and added atoms form a blended structure, and the formation of the structure improves the roughness of the surface of the polymer and increases the bonding strengthof the polymer and metal, so the peel strength of the polymer is enhanced. According to the treatment method, the surface resistivity, the surface roughness, the water absorbency and the tensile property of the polymer can be considered at the same time, used equipment is long in service life and low in cost, large-scale roll-to-roll production can be achieved, and the method can be popularized inpolymer surface treatment.

Description

technical field [0001] The invention relates to the technical field of polymer surface treatment, in particular to a method for surface treatment of polymers for 5G. Background technique [0002] With the development of science and technology, polymers are more and more widely used in the field of science and technology, and their importance has become increasingly prominent. The polymer itself has very unique properties, such as excellent corrosion resistance, high and low temperature resistance, aging resistance, physical and chemical inertness, and high insulation properties. But in many cases, the polymer itself is not used alone, it needs to be coupled with other metals, non-metals, metal oxides, etc. Therefore, higher requirements are put forward for the adhesive properties of polymer surfaces, especially in some applications that require high bonding interface strength. It is difficult for conventional polymers to meet their bonding requirements, which greatly limits...
