Abstract

The invention provides an intelligent window and a preparation method thereof, and relates to the field of new materials. The intelligent window comprises two PEDOT: PSS film electrodes and an electrolyte packaged between the two PEDOT: PSS film electrodes, each PEDOT: PSS film electrode comprises a substrate and a PEDOT: PSS suspension liquid coating arranged on the surface of the substrate, PEDOT: PSS suspension liquid is prepared from ethylene glycol, PH1000 and a fluorine-containing surfactant, the electrolyte comprises a phosphoric acid electrolyte or a phosphoric acid gel electrolyte, and the PEDOT: PSS suspension liquid coating is coated on the surface of the substrate. The phosphoric acid electrolyte is prepared from a phosphoric acid solution, deionized water and ethylene glycol, and the phosphoric acid gel electrolyte is prepared from polyvinyl alcohol and the phosphoric acid electrolyte. According to the intelligent window, the transmittance of solar near-infrared radiation energy can be remarkably regulated and controlled, electrochemical energy storage can be achieved, the visible light transparency is high, all-weather work can be achieved, and the stability is good.

Description

technical field [0001] The invention relates to the field of new materials, in particular to a smart window and a preparation method thereof. Background technique [0002] Climate change and global warming have become the number one existential crisis faced by human beings. Against this background, green, low-carbon, energy-saving and emission-reduction have become the focus of global attention. From the perspective of energy consumption industries, construction, industry, and transportation are recognized globally as the three high-energy-consuming areas. With the acceleration of my country's urbanization process and the improvement of people's quality of life, building energy consumption is constantly increasing. Relevant reports show that 50% of building energy consumption is used for space cooling and heating and lighting. The main cause of space overcooling or overheating is related to the uncontrollable light and heat conduction of building windows, especially the near...
