How to optimize the coating structure of PET gold plating film to improve its anti glare performance?

PET gold-plated film, as a composite material coated with a thin layer of gold on the surface of polyethylene terephthalate (PET) film, has been widely used in various fields such as electronic devices, flexible circuit boards, and flexible displays due to its excellent conductivity, corrosion resistance, and decorative effect. However, in certain specific application scenarios, such as screen protection,PET gold-plated filmExcellent anti glare performance is also required to ensure clear and interference free image quality. This article will explore how to improve the anti glare performance of PET gold plating film by optimizing its coating structure, and introduce the technological progress of Advanced Institute (Shenzhen) Technology Co., Ltd. in this field.

Optimization strategy for coating structure

1. Optimize PET substrate material

   • Enhancing substrate toughness: By improving the formulation or production process of PET materials, such as adding appropriate toughening agents or anti bending agents, the toughness and anti bending performance of PET itself can be improved, thereby reducing the risk of coating rupture during bending or folding processes.

   • Improving substrate surface energy: PET material has low surface energy and a certain degree of chemical inertness, resulting in relatively weak adhesion between it and the coating. Therefore, surface modification techniques such as plasma treatment, chemical etching, etc. can be used to improve the activity of PET surface and enhance its adhesion to the coating.

2. Choose the appropriate coating material

   • Choose a coating material with a thermal expansion coefficient similar to that of the PET substrate to reduce thermal stress caused by temperature changes, thereby reducing the risk of coating cracking.

   • The coating material should have good corrosion resistance and conductivity, while also considering its reflection and scattering characteristics of light to reduce glare.

3. Control the thickness of the coating

   • The thickness of the coating has an impactPET gold-plated filmThe key factors of conductivity, corrosion resistance, and mechanical properties. Experimental data shows that as the thickness of the gold plating layer increases, the conductivity of PET gold plating film is significantly improved, and its corrosion resistance is also enhanced. However, excessive coating may alter the shape and size of PET film, affecting assembly accuracy with other components and increasing costs.

   • Therefore, the appropriate coating thickness should be selected according to specific needs to balance multiple factors such as conductivity, corrosion resistance, cost, and assembly accuracy.

4. Optimize sedimentary parameters

   • During the sputtering coating process, parameters such as deposition rate, deposition temperature, power, and working pressure should be adjusted reasonably to reduce film stress and improve coating quality.

   • By stepwise deposition or multi-layer structural design, stress can be further dispersed and reduced, improving the stability and anti glare performance of the coating.

5. Apply anti glare coating

   • Coating a layer of anti glare coating on the surface of PET gold-plated film can effectively reduce the reflection and scattering of light sources on the screen, and reduce glare phenomenon.

   • Anti glare coatings should be composed of monomers with anti glare properties, such as acrylic esters, hydroxybenzoate esters, etc., and coated and cured under appropriate process conditions.
