The influence of surface roughness of PET silver plated reflective film on its reflective performance

PET silver plated reflective filmAs a high-performance optical film, it has been widely used in various fields such as photoelectric sensors, solar energy, lighting, and display. Its high reflectivity, good flexibility, and weather resistance make it one of the key materials for improving the performance of related equipment. However, the surface roughness of PET silver plated reflective film has a significant impact on its reflective performance, which is often overlooked. This article will delve into how the surface roughness of PET silver plated reflective film affects its reflective performance, and provide explanations based on relevant technology and product data from Advanced Institute (Shenzhen) Technology Co., Ltd.

1、 Basic characteristics of PET silver plated reflective film

PET silver plated reflective film is a thin film coated with a layer of silver on the surface of PET (polyethylene terephthalate) as the substrate. The reflectivity of this film in the visible light range can reach over 80% to 97%, and some products can even reach over 90%. At the same time, it also has a high transmittance of about 70%, which means that in specific application scenarios, light energy can be effectively preserved and utilized. In addition, PET material itself has good flexibility and weather resistance, which can effectively protect silver film from environmental influences and extend its service life.

2、 The influence of surface roughness on reflection performance

Surface roughness is an important indicator for measuring small geometric errors on the surface of materials. aboutPET silver plated reflective filmIn terms of surface roughness, it directly affects the uniformity and directionality of reflected light.

1. Affects the uniformity of reflected light: When the surface roughness of PET silver plated reflective film is large, the reflected light will scatter, resulting in a decrease in the uniformity of reflected light. This will affect the sensitivity of photoelectric sensors, reduce the photoelectric conversion efficiency of solar cells, and affect the display effect of lighting and display devices.
2. Affects the directionality of reflected light: Surface roughness can also affect the directionality of reflected light. When the surface roughness is small, the reflected light is more concentrated and has better directionality. This helps to more accurately capture and focus light in photoelectric sensors, improving image clarity and resolution. In the field of lighting and display, it can improve lighting efficiency and display brightness.
