Preparation method of fluorescent coded microspheres

The invention discloses a preparation method of fluorescent coded microspheres and belongs to the technical field of function materials. According to the preparation method, a dispersion polymerization in-situ coating method is adopted, azodiisobutyronitrile (AIBN) is used as an initiator, polyvinylpyrrolidone (PVP) is used as a dispersing agent, ethyl alcohol and water are used as mixed solvents, glycidyl methacrylate (GMA) polymerization is induced to clathrate fluorescence probe molecules under nitrogen protection, and the monodisperse high-performance PGMA fluorescent coded microspheres uniform in morphology and controllable in size are prepared. The clathration effect of polymer palletization and epoxy groups inside the microspheres are utilized to fix the fluorescence probe molecules in the process, so that the fluorescence molecules are not easily leaked and have stable and lasting luminous capability. The preparation method is simple and convenient, the obtained microspheres can be stably dispersed in
