Preparation method of self-adaptive optical gel based on boric acid ester reversible covalent bonds

The invention relates to a preparation method of optical gel with self-adaptive characteristics, and the optical gel is obtained by adding a comonomer, a small molecular functional monomer containingphenylboronic acid functional groups, complementary macromolecules and an initiator into a dispersion liquid of monodisperse microspheres under a specific pH condition, and then carrying out ultraviolet light or thermal polymerization, wherein the pH value is between 6 and 10. The monodisperse microspheres comprise inorganic microspheres, silicon dioxide microspheres, ferroferric oxide microspheres, titanium dioxide microspheres and the like; organic microspheres, polystyrene (PS) microspheres, polymethyl methacrylate (PMMA) microspheres and the like; the hybrid microspheres comprise core-shell structure microspheres and the like; and the particle size of the monodisperse microspheres ranges from 80nm to 3mu m. The particle size of the monodisperse microspheres determines the color presented by the optical gel, and the smaller the particle size is, the color moves towards the blue direction, otherwise, the color moves towards the red direction.
