Enhance the resistance of PET gold-plated reflective film to ultraviolet (UV) radiation

With the rapid development of optoelectronic technology, the application of PET gold-plated reflective film in optical systems, LED displays, solar cells and other fields is becoming increasingly widespread. However, the impact of ultraviolet (UV) radiation on these materials cannot be ignored, as it may lead to material aging, discoloration, and even performance degradation. Therefore, enhancePET gold-plated reflective filmThe tolerance to ultraviolet radiation has become a current research hotspot. This article will provide a detailed introduction to several technical methods for improving the UV resistance of PET gold-plated reflective films, and specifically mention the contribution of Advanced Institute (Shenzhen) Technology Co., Ltd. in this field.

1、 Select UV resistant additives

Adding anti UV additives is an effective method in the preparation process of PET gold-plated reflective film. These additives, such as UV absorbers or light stabilizers, can effectively absorb or reflect UV radiation, thereby reducing the destructive effect of UV radiation on materials. The anti ultraviolet additive compounded by Advanced Institute (Shenzhen) Technology Co., Ltd. through a special process can significantly improve the anti-aging ability and weather resistance of PET gold-plated reflective film and extend its service life.

2、 Surface modification treatment

1. Plasma treatment

Plasma treatment is a method of generating plasma at low temperatures by introducing active gas moleculesPET gold-plated reflective filmThe method of surface bombardment. This method can effectively activate the PET surface, promote the adhesion of subsequent coatings, reduce interface defects, and improve the adhesion between the gold plating layer and the PET substrate. In addition, plasma treatment can improve the wettability and adhesion of PET surface, which is beneficial for the subsequent coating and curing of UV resistant coatings.

2. Chemical plating

By depositing a uniform and dense functional coating on the surface of PET gold-plated reflective film through chemical reactions, such as inorganic nanoparticles such as silica (SiO ₂) or alumina (Al ₂ O3), its UV resistance can be further improved. These coatings can not only fill the microporous structure on the surface of PET, but also form a composite barrier effect with the gold plating layer, reducing the penetration and damage of ultraviolet rays to the material.

3、 Multi layer composite structure design

Adopting a multi-layer composite structure design is another effective method to improve the UV resistance of PET gold-plated reflective films. By alternately stacking two or more thin film materials with different properties, a microstructure with gradient changes can be constructed, which can significantly enhance the overall barrier performance of the material without affecting transparency. For PET gold-plated reflective film, several layers of different thicknesses and compositions of barrier layers can be sequentially coated on its surface, such as organic-inorganic hybrid materials, polymer nanofibers, etc., to achieve better comprehensive protection effect.

4、 Optimize gold plating process

Optimizing the gold plating process is also the key to improving the UV resistance of PET gold plated reflective films. During the gold plating process, the composition, temperature, pH value, and other parameters of the gold plating solution are strictly controlled to ensure the uniformity and density of the gold plating layer, thereby improving its ability to reflect and block ultraviolet rays.

5、 Strengthen quality control

Strengthening quality control is an important measure to ensure the UV resistance of PET gold-plated reflective film during its preparation process. This includes strictly controlling the quality of raw materials, optimizing production process parameters, strengthening environmental monitoring and finished product testing during the production process, etc.Advanced Institute (Shenzhen) Technology Co., LtdWith its advanced production equipment and strict quality management system, it can provide customers with high-quality PET gold-plated reflective film products.
