Properties
Description
This broad category of materials involves various ferrimagnetic or superparamagnetic cores (such as Fe3O4 or MnFe2O4) stabilized by a PEG polymer corona. The PEG shell is engineered to provide high osmotic pressure and steric repulsion, preventing the magnetic cores from clumping under the influence of magnetic dipoles. This architecture ensures the material remains as a stable colloidal suspension even under high-shear industrial mixing conditions.
