| titleOfInvention | Flexible photonic crystal with multi-angle photochromic effect and preparation method thereof |
| abstract | The invention belongs to the technical field of intelligent response materials, in particular to a flexible photonic crystal with multi-angle photochromic effect and a preparation method thereof. The flexible photonic crystal material of the present invention is a three-layer thin film composite: PET film-photochromic photonic crystal film-PET film; the preparation steps include: synthesizing an emulsion of monodisperse core-shell polymer microspheres, drying by demulsification The solid microspheres are obtained, and then the solid microspheres and the photosensitive pigment are mixed and banburyed in an internal mixer; the microspheres obtained by banburying are compounded with the release PET film by a flat vulcanizer, and the composite film is produced by bending and inducing regularity to produce bright colors. color. The microsphere structure includes a hard core layer, a connecting intermediate layer and a soft shell layer; the photochromic pigment is a microcapsule particle. The film prepared by the invention is sensitive to sunlight and ultraviolet light, and can produce different discoloration effects under illumination and ultraviolet light at different angles, and has great potential application in the fields of display, decoration, information encryption and the like. |
