Developed by the postdoctoral workstation at Shenzhen JiSu Smart Tech Co., Ltd., the new intelligent, reversible, electrically controlled, color-changing Dimming Film material, known as EPC (Electric Polarized Crystal) fabrication Technology, is a film-forming photoelectric material composed of polarized crystals suspended and dispersed within a polymer network.
This material achieves both light blocking and light transmission by inducing charge electroosmosis, exploiting the specific movement and arrangement of charged particles under the influence of an electric field. In the absence of voltage, the particles are evenly distributed, reflecting and scattering light, resulting in a dark state. When voltage is applied, the particles move in the direction of the electric field, forming aggregates that reduce light reflection and scattering, significantly increasing light transmittance and resulting in a bright state.
