How to enhance the flexibility of PET gold-plated reflective film without affecting its reflective performance

PET gold-plated reflective filmDue to its excellent reflective performance, good mechanical strength, and chemical stability, it is widely used in various fields such as optoelectronic devices, solar energy collection, lighting systems, display technology, etc. However, in certain applications, PET gold-plated reflective films require higher flexibility to adapt to complex curved structures or frequent bending operations. So, how to enhance the flexibility of PET gold-plated reflective film without affecting its reflective performance? This article will explore this issue and introduce the research achievements of Advanced Institute (Shenzhen) Technology Co., Ltd. in this field.

1、 Basic Structure and Properties of PET Gold Plated Reflective Film

The PET gold-plated reflective film is mainly composed of a PET substrate and a gold-plated layer. PET substrate has good flexibility and mechanical properties, while the gold plating layer endows it with excellent reflective properties. However, the brittleness of the gold plating layer is relatively high, and it is prone to cracking when frequently bent or subjected to external forces, which affects its reflection performance. Therefore, enhancing the flexibility of PET gold-plated reflective film requires starting from two aspects: substrate and coating.

2、 Methods to Enhance the Flexibility of PET Gold Plated Reflective Film

1. Optimize the formula and processing technology of PET substrate

By optimizing the formula and processing technology of PET substrate, its flexibility can be significantly improved. For example, an appropriate amount of plasticizer can be added to PET substrate to lower its glass transition temperature, allowing it to maintain good flexibility even at lower temperatures. In addition, the use of biaxial stretching process can improve the molecular orientation of PET substrate, thereby enhancing its mechanical properties and flexibility.

2. Adopting a multi-layer composite structure

Adopting a multi-layer composite structure is also a form of reinforcementPET gold-plated reflective filmAn effective method of flexibility. For example, a soft intermediate layer such as polyurethane or silicone can be added between the PET substrate and the gold plating layer. This intermediate layer not only serves as a buffer to reduce the impact of external forces on the gold plating layer, but also enhances the bonding strength between the gold plating layer and the PET substrate, thereby improving the overall flexibility and reflective performance.

3. Improve the microstructure of the gold plating layer

By improving the microstructure of the gold plating layer, its flexibility can also be enhanced. For example, nano gold particles can be used instead of traditional gold particles to increase the flexibility and ductility of the gold plating layer. In addition, the use of multi-layer gold plating technology, which involves sequentially depositing multiple thin gold films on PET substrates, can also improve the overall flexibility and reflective performance of the gold plating layer.

Advanced Institute (Shenzhen) Technology Co., Ltd. has achieved significant results in enhancing the flexibility of PET gold-plated reflective films. The company has successfully prepared PET substrates with excellent flexibility by optimizing the formula and processing technology of PET substrates. At the same time, the company adopts a multi-layer composite structure and nano gold particle gold plating process, significantly improving the flexibility and reflective performance of PET gold plated reflective films.

The experimental results show that after optimizationPET gold-plated reflective filmAfter repeated bending for 1000 times, its reflectivity can still remain above 98%, far higher than the reflectivity of traditional PET gold-plated reflective films. In addition, the company's PET gold-plated reflective film also has good chemical corrosion resistance and anti-aging performance, which can maintain its excellent performance in harsh environments for a long time.

4、 Conclusion

Enhancing the flexibility of PET gold-plated reflective film without affecting its reflective performance is a challenging task. By optimizing the formula and processing technology of PET substrate, adopting multi-layer composite structure, and improving the microstructure of the gold plating layer, the flexibility and reflective performance of PET gold plating reflective film can be significantly improved.
