The conductivity of conductive film generally ranges from 10^2 to 10^7 S/m. The specific value depends on the material composition, preparation process and application environment of the conductive film.
The conductivity range of different types of conductive films
ITO conductive film: The resistivity of ITO (Indium Tin Oxide) conductive film is between 10⁻⁴ and 10⁻³ Ω·cm, and the corresponding conductivity is relatively high.
Graphene composite conductive film: The conductivity of graphene composite conductive film is 500-800 S/cm and the thickness is 10-20 μm.
Highly conductive carbon nanotube film: The conductivity of highly conductive carbon nanotube film is (1-10)x10^4 S/m and the thickness is 5-15 μm.
Factors affecting the conductivity of conductive films
Material composition: Different materials (such as metals, metal oxides, carbon materials, etc.) have different conductive mechanisms, so their conductivity will also vary.
Preparation process: The preparation process such as film thickness, uniformity, crystallinity, etc. will affect the conductivity. Optimizing the preparation process can improve the conductivity of the conductive film.
Application environment: Environmental factors such as temperature, humidity, and pressure may change the internal structure of the conductive film, thereby affecting its conductive properties.
