A surface treatment production process for a polymer film, comprising: taking 10wt% polyvinyl alcohol, 4wt% citric acid and 2wt% branched polyethyleneimine each, mixing with ultrapure water and stirring until completely dissolved, keeping The solution PH∈[2.7, 5.2], and the temperature was kept at 120-140°C for 10-30min microwave synthesis. After adjusting the concentration of the solution, a 15wt% modified liquid was prepared; the modified liquid was sprayed on the PET film and dried to complete Modification of the PET film to obtain an ultra-thin PET modified film; image recognition of the modified film to determine the modification situation. Thereby, an ultra-thin PET film with high ultraviolet blocking rate and high visible light transmittance can be obtained. |
