Soft chemistry (also known as chimie douce) is a type of chemistry that uses reactions at ambient temperature in open reaction vessels with reactions similar to those occurring in biological systems.
A dual-ion modified Bi2WO6 electrochromic thin film material and a preparation method thereof
ActiveCN118373606BExcellent electrochromic performanceIncreased Optical Modulation AmplitudeThin membraneElectrochromism
The application discloses a kind of double ion modified Bi2WO6 electrochromic thin film materials and preparation method thereof, and relates to the field of electrochromic thin film.The preparation method of the application includes the following steps: (1) hydrothermal controllable preparation Bi2WO6 Nanometer powder;(2) using hydrogen ion and alkali metal ion to Bi2WO6 Nanometer powder is carried out double ion replacement reaction to modify Bi2WO6 Crystal lattice structure;(3) the Bi2WO6 Nanometer powder after double ion modification is made into the nanometer dispersion liquid with good dispersibility, then double ion modified Bi2WO6 electrochromic thin film material is obtained by spin coating process.The method retains the key structural characteristics of precursor phase by soft chemical modification, and the double ion modified Bi2WO6 electrochromic thin film shows excellent electrochromic performance in near-infrared band, and the optical modulation amplitude is greatly increased.The preparation method is simple, safe and controllable, low in cost, and has wide application prospect.
