Problems solved by technology

However, the conductive oxide nanoparticles in this patent have a very strong absorption of far infrared, resulting in relatively weak adjustment ability for mid-far infrared.
Conductive oxide nanoparticles have strong absorption in the mid- and far-infrared due to the surface plasmon resonance effect, so they can only adjust visible light and near-infrared light.

Abstract

The invention discloses a visible-infrared independent control electrochromic device. The structure of the visible-infrared independent control electrochromic device comprises a first transparent electrode, a first electrochromic layer for only regulating visible light under a high-voltage condition, a second electrochromic layer for only regulating infrared light transmittance under a low-voltagecondition, an ion conduction layer and a second transparent electrode which are arranged in sequence, wherein the high voltage ranges from-5 V to 5 V, and the low voltage ranges from-2.5 V to 2.5 V.The first electrochromic layer capable of adjusting visible light and the second electrochromic layer capable of only adjusting infrared light are designed, so that the transmittance of the infrared light and the transmittance of the visible light are independently adjusted and controlled under different voltages, and the requirements of actual life are met.

Description

technical field [0001] The invention relates to the technical field of chemical material synthesis and functional materials, in particular to a visible-infrared independently regulated electrochromic device. Background technique [0002] Energy is an important basis for maintaining the sustainable development of the national economy and ensuring the material living standards of the people. Nowadays, problems such as energy shortage and environmental pollution are becoming more and more serious. While developing new energy sources, scientists are also trying to find ways to save energy and reduce consumption. Buildings are one of the main places where human beings carry out production and living activities. In the total energy consumption of human production and life, building energy consumption accounts for a large proportion. consumption, accounting for more than 75% of the total building energy consumption. The energy consumption of these two parts is related to door and...
