Spherical polyelectrolyte brushes with embedded magnetite nanoparticles in core were synthesized successfully by photo-emulsion polymerization. Magneviscous behavior can be observed for these magnetic brushes as well as the magnetic PS core before grafting PAA brushes. Their viscosity can be tuned by the external magnetic field strength.
