The invention relates to a fluorescent polymer composition, fluorescent powder, preparation method and application in the polymer field. The fluorescent polymer composition is composed of a blue fluorescent polymer and a red fluorescent polymer with a weight ratio of 10:90 to 90:10; the blue fluorescent polymer is a maleic anhydride copolymer of a specific general formula modified by strong alkali. The red fluorescent polymer is obtained after heat treatment of the blue fluorescent polymer. Its fluorescence characteristics include both 400-550nm blue light emission and 600-750nm red light emission. The fluorescent polymer composition, fluorescent powder and light-converting resin thereof have high fluorescence intensity, low cost of raw materials, mature technology, no biological toxicity and environmental pollution, good water solubility or water dispersibility, various application forms, and easy industrialization. promotion. It has broad application prospects in the fields of anti-counterfeiting, biological imaging, light conversion films, ultraviolet light absorbing materials, solar cell sealants, fluorescent dyes and other fields. |
