Abstract

The invention discloses a macromolecular magnetic composite material. Magnetic nano ferroferric oxide particles are introduced into the composite material and are loaded on the surface of the composite material, so that the dispersity of ferroferric oxide can be improved, and the problem that a conventional adsorbent material is difficult to separate and recycle from a reaction system is effectively solved. By the adoption of macromolecular auxiliaries such as polytetrahydrofuran glycol and sodium polyacrylate, the dispersity of ferroferric oxide in the composite material is effectively improved, and the added polyimide effectively enhances the surface strength of a finished product. The magnetic material disclosed by the invention can be widely applied to the fields such as magnetic targeting medicine carrying, biological separation and magnetic resonance imaging.
