| titleOfInvention | Preparation method of magnetic microspheres with uniform particle size |
| abstract | The invention relates to the technical field of high polymer materials, and provides a preparation method of magnetic microspheres with uniform particle size, which comprises the following steps: (1) preparing magnetic fluid; (2) performing magnetic fluid chemical modification by olefin; (3) swelling; (4) preparing an aqueous phase; (5) and (4) preparing magnetic microspheres. The problems that the magnetism of the magnetic fluid is easy to lose and the particle size distribution is wide in the prior art are solved. |
