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 field of glass technology and metal nanomaterials, and specifically relates to a new type of electrochromic glass. Background technique [0002] Electrochromism refers to the phenomenon of reversible oxidation or reduction of a material due to changes in the polarity and intensity of an applied electric field, resulting in a change in its 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 reflectance, transmittance, and absorptivity. The appearance is expressed as a reversible change in glass color and transparency to achieve dimming purpose. This kind of smart color-changing glass only needs to adjust the light transmittance of the glass under the action of voltage, and can be adjusted to different levels of light transmittance under the action of different voltages; the state of the glass can be maintained for ...
