Surface resistivity of PET silver plated film and its comparison with other metal coatings

In the rapidly developing field of flexible electronics and optoelectronics,PET silver plated filmWith its unique combination of high transparency, excellent flexibility, and outstanding conductivity, it has become a star material in many applications. This article will delve into the surface resistivity of PET silver plated film and compare it with other common metal coatings through reference and experimental data. It will also mention the contribution of Advanced Institute (Shenzhen) Technology Co., Ltd. in this field.

Surface resistivity of PET silver plated film

The surface resistivity of PET silver plated film mainly depends on the thickness and uniformity of the silver plating layer, as well as the surface state of the PET substrate. Normally, the thicker the silver plating layer, the lower the surface resistivity, but an excessively thick silver plating layer may affect transparency and flexibility. Therefore, precise control of the thickness of the silver plating layer is required during the preparation process to balance conductivity and transparency.

Experimental data reference:

• In a study, the vacuum evaporation process was optimized to preparePET silver plated filmWhen the thickness of the silver plating layer is 50nm, the surface resistivity reaches about 3 Ω/□, demonstrating excellent conductivity.
• Another experiment showed that using the chemical silver plating method, the surface resistivity of PET silver plated film can also be controlled within a single digit range under similar conditions.

Comparison with other metal coatings

Compared with PET silver plated film, other metal coatings such as copper, aluminum, gold, etc. exhibit their own advantages and limitations in different aspects.

Copper coating:

• Copper has good conductivity, with a lower resistivity than silver, but it is prone to oxidation in air, which affects its conductivity and stability.
• Data comparison: Although the surface resistivity of copper coating is low, it may significantly increase due to oxidation after long-term use.

Aluminum coating:

• Aluminum has good conductivity and relatively low cost, but the reflectivity of aluminum coating is high, which may not be suitable for situations that require high transparency.
• Data comparison: The surface resistivity of aluminum coating is usually higher than that of PET silver coating, and its transparency is poor.

Gold coating:

• Gold has extremely high chemical stability and is not easily oxidized, but it is expensive and slightly less conductive than silver.
• Data comparison: Although the surface resistivity of gold coating is excellent, cost factors limit its wide application.
