Conductive film structure used for smart film

Abstract

The invention discloses a conductive film structure used for a smart film. The structure is characterized by comprising a base film layer, a first light-transmittable conductive film layer, and a second light-transmittable conductive film layer, wherein the first light-transmittable conductive film layer is arranged on the base film layer and used for reducing the resistance value and has a first optical refractive index; the second light-transmittable conductive film layer is arranged on the first light-transmittable conductive film layer and has a second optical refractive index; the first light-transmittable conductive film layer is located between the base film layer and the second light-transmittable conductive film layer; and the first optical refractive index is lower than the second optical refractive index. The conductive film structure provided by the invention is low in surface resistance, high in light transmission, and low in radiation (high in visible light transmission and low in infrared light transmission), and has an energy-saving function. When the conductive film structure is applied to the smart film, the overall value and performance of the smart film can be improved substantially.

Description

technical field [0001] The invention relates to a conductive film structure, in particular to a conductive film structure used for a dimming film. Background technique [0002] The traditional dimming film (PDLC or SmartFilm) mainly uses the transparent conductive film on it to control whether the light penetrates or not by means of power-on and power-off. Specifically, since the liquid crystal molecules of the dimming film are randomly arranged when the transparent conductive film is powered off, when the light enters the dimming film, the scattered liquid crystal molecules will block the light, then At this time, the dimming film has the effect of shielding light. On the other hand, when the transparent conductive film is energized, the liquid crystal molecules of the dimming film will be arranged in a regular shape, so light can penetrate the dimming film within a fixed range to achieve the purpose of seeing through the dimming film.

AI Technical Summary

Problems solved by technology

However, when wanting to reduce the surface resistance, the thickness of the sputtered film layer 13 needs to be greatly increased, so that the light transmittance of the transparent conductive film 1 will be reduced, and the overall light transmittance of the dimming film will be poor.

What's more, since the material of the transparent conductive film used in the prior art dimming film does not have the effect of Low-E (low-E, characterized by high penetration of visible light and low penetration of infrared rays), its energy-saving effect is higher than that of light transmission. It is also poor in transparent state
