The present application discloses a surface treatment method of a polymer for 5G, belonging to the technical field of surface treatment of polymer. By injecting and adding the oxygen elements to the polymer, the polymer matrix elements and the injected atoms can form a blend structure, which can increase the surface roughness of the polymer, improve its bonding strength with the metal, and thus enhance its anti-peel strength. The surface treatment method of the application has the surface resistivity, surface roughness, water absorption and tensile properties of the polymer all considered. The equipment used in the invention has long service life and low cost, and can realize large-scale roll-to-roll production. The method can be popularized in polymer surface treatment.
