Abstract

The invention discloses intelligent photochromic glass with plasmon broad-spectrum regulation and control functions. The intelligent photochromic glass is characterized in that each polymer molecular brush material layer (6) between a lower silver nano-wire electrode (31) and an upper silver nano-wire electrode (32) comprises an upper portion and a lower portion, the upper silver nano-wire electrodes (32) are connected with the upper sides of the upper portions of the polymer molecular brush material layers (6), and plasmon nano-particles (5) are connected with the lower sides of the upper portions of the polymer molecular brush material layers (6); the lower silver nano-wire electrodes (31) are connected with the lower sides of the lower portions of the polymer molecular brush material layers (6), and plasmon nano-particles (5) are connected with the upper sides of the lower portions of the polymer molecular brush material layers (6); spaces which are formed by the polymer molecular brush material layers (6) and the plasmon nano-particles (5) and are formed by the polymer molecular brush material layers (6) and silver nano-wire electrodes (3) are filled with transparent liquid (4); two ends of each peripheral driving circuit (7) are connected with the corresponding lower silver nano-wire electrode and the corresponding upper silver nano-wire electrode. The intelligent photochromic glass has the advantages that scattering spectra of the intelligent photochromic glass can be dynamically regulated from visible light wave bands to infrared wave bands, the intelligent photochromic glass is high in response speed and low in cost, processes for manufacturing the intelligent photochromic glass are simple, and the like.

Description

technical field [0001] The invention belongs to the fields of glass technology and metal nanomaterials, and in particular relates to a novel electrochromic glass. Background technique [0002] Electrochromism refers to a phenomenon in which a material undergoes a reversible oxidation or reduction reaction due to changes in the polarity and strength of an applied electric field, resulting in a change in color. At present, as a new type of energy-saving glass, electrochromic glass uses an external electric field to change the optical properties of the material such as reflectivity, transmittance and absorptivity, and the appearance shows reversible changes in glass color and transparency to achieve dimming Purpose. This kind of intelligent color-changing glass only needs to adjust the light transmittance of the glass under the action of voltage, and can adjust to different levels of light transmittance under different voltages; after removing the applied voltage, the state of...
