| Abstract: |
| The purpose of surface modification of polyethylene (PE) film is to introduce polar groups on the surface, so as to improve the surface roughness of the film, and eliminate the weak interface layer, thus improving the surface energy of the film. Several surface modification methods of polyethylene film were reviewed, including chemical modification, flame and heat treatment, surface grafting, plasma treatment, corona treatment, blending modification and interaction method, and the advantages and disadvantages of each modification method were compared. PE is a non-polar material with low surface energy (30~32 dynes/cm). Its surface is inert and hydrophobic, so it is not easy to be composite or mixed with other materials. Therefore, it is of poor hydrophilicity, printability, dyeing, antistatic property, adhesion, and compatibility with other polar polymers or inorganic fillers, which limits the further application of PE. This paper shows and compares the surface modification of polyethylene film comprehensively through literature search, effect and mechanism analysis, comparison, review and other methods. The chemical modification, flame and heat treatment, surface grafting, plasma treatment, corona treatment, blending modification and co-treatment method have been reviewed, with their advantages and disadvantages compared. The chemical method and blending method are easy to operate. Moreover, the chemical method, grafting method and blending method can maintain stable effects. In addition, the co-treatment method has mild operation conditions and long-lasting effect. The surface energy of 38 dynes/cm can be maintained for more than three months when the additive content is 1000 mg/L. The additive is stable to the polar solvent and does not affect the performance of PE bulk. Therefore, the research is of great potential in industrial application. |
