| titleOfInvention | Preparation method of surface cation polystyrene microspheres |
| abstract | The invention discloses a preparation method of surface cation polystyrene microspheres, belonging to the technical field of materials and comprising the following steps: taking styrene as an initial monomer, taking ethanol/water as a mixed dispersion medium, adding an initiator and a dispersing agent, reacting in a nitrogen atmosphere, then adding a cationic functional monomer and an ethanol/water medium mixture, continuing to react, and washing and drying after the reaction is finished to obtain the cationic functional monomer; the system has better stability, and Zeta potential values are all more than +25 mV; the preparation process is simple, the prepared functional polystyrene microsphere has good monodispersity, the particle size of the microsphere is adjustable and controllable, the high-efficiency enrichment of functional groups on the surface of the microsphere can be realized, the particle size distribution of the prepared microsphere is narrow, and the variation coefficient is below 0.6%. |
