| titleOfInvention | Rare earth polyelectrolyte composite particle and preparation method thereof |
| abstract | The invention discloses a rare earth polyelectrolyte composite particle and a preparation method thereof, wherein the preparation method comprises the following steps: the first step is as follows: preparing polyelectrolyte composite particles; dissolving a cationic polymer and an anionic polymer by using a solvent, mixing the cationic polymer and the anionic polymer in a dropwise manner for reaction, stirring for 3-5 hours after dropwise addition is completed to enable the cationic polymer and the anionic polymer to fully react, standing the reacted solution overnight, centrifuging, washing and storing to obtain a polyelectrolyte composite particle solution; the second step is that: preparing rare earth polyelectrolyte composite particles; dissolving europium chloride by adopting a solvent, dropwise adding a europium chloride solution into the polyelectrolyte composite particle solution obtained in the first step, dropwise adding a TTA solution after 30-50 minutes, adjusting the pH value of the solution after 30-50 minutes, dropwise adding a phenanthroline solution, and stirring for 2-4 hours to obtain the rare earth polyelectrolyte composite particles with fluorescence performance. The preparation method is simple and easy to implement, and the prepared rare earth polyelectrolyte composite particles have strong fluorescence intensity and wide application range. |
