The surface treatment of the substrate does have an impact on the friction resistance of PET gold-plated film

1、 Basic characteristics of PET material

PET (Polyethylene terephthalate)It is a polymer material with excellent physical and mechanical properties and electrical insulation. It has high tensile strength, good fatigue resistance, friction resistance, and dimensional stability, and can maintain stable performance over a wide temperature range. However, the surface structure of PET is highly symmetrical and the molecules have special characteristics, which may make it difficult for some coatings or coatings to tightly bond with it.

2、 The role of substrate surface treatment

In order to increase the adhesion between PET substrate and upper layer materials (such as gold plating), surface treatment of PET is usually required. This treatment can improve the wettability of PET, allowing the treatment agent (such as primer) to achieve a tight bond with PET molecules. At the same time, the treatment agent can also interact with the upper coating (such as the gold plating layer) to form a strong bonding layer, thereby improvingPET gold-plated filmThe friction resistance performance.

3、 The Effect of Surface Treatment on Friction Resistance Performance

1. Increasing adhesion: By surface treatment, the adhesion between PET substrate and gold plating layer can be significantly improved. This improvement in adhesion helps prevent the gold plating layer from falling off or wearing out when subjected to friction, thereby enhancing the friction resistance of PET gold plating film.
2. Improving surface hardness: Some surface treatment techniques, such as plasma surface treatment, can also improve the hardness and wear resistance of PET material surfaces. This increase in hardness helps reduce friction damage to the surface of PET gold plating film, thereby extending its service life.
3. Maintain performance stability: PET gold-plated film with appropriate surface treatment can maintain stable performance during long-term use. This means that its friction resistance will not significantly decrease over time.

4、 Considerations in practical applications

In practical applications, it is necessary toPET gold-plated filmChoose the appropriate surface treatment technology based on its specific purpose and requirements. For example, for PET gold plating films that require high friction resistance, surface treatment techniques that can significantly improve adhesion and hardness can be chosen. At the same time, it is necessary to consider the processing cost, processing efficiency, and the impact of processing on other properties of PET gold plating film, such as electrical and thermal properties.

In summary, surface treatment of the substrate has a significant impact on the friction resistance of PET gold-plated film. By selecting appropriate surface treatment techniques, the adhesion and hardness of PET gold plating film can be significantly improved, thereby enhancing its friction resistance and service life.
