METHOD FOR MANUFACTURING MAGNETIC PARTICLE COMPOSITE

摘要

Disclosed is a method for manufacturing a magnetic particle composite, which comprises the following steps: providing magnetic nanoparticles; providing water-soluble macromolecules, and dissolving the water-soluble macromolecules to form a water-soluble macromolecular solution; uniformly mixing the magnetic nanoparticles with the water-soluble macromolecular solution to form a first mixed solution; providing a dispersed solution, and uniformly mixing the dispersed solution with the frrst mixed solution to form a second mixed solution; and finally adding a hardener into the second mixed solution to form a magnetic particle composite. This manufacturing method is used to form a magnetic particle composite through control of boundary tension between immiscible liquid phases and to control the particle size of a finished product. Therefore, magnetic particle composites of different particle sizes and different saturation magnetization values can be manufactured by using a simple process at a low cost.
