Abstract

This chapter summarizes the recent advances on the self-assembled magnetic nanoparticle-polymer composite materials. This class of composite materials has gained significant attention owing to their unique stimuli-responsive behavior under internal and external magnetic fields. After a brief introduction of magnetism associated with magnetic materials, we outline the various approaches that have been investigated to synthesize magnetic nanoparticle-polymer composites with well-controlled one-, two- and three-dimensional architectures. This chapter also highlights promising future applications of these composite materials, including magnetic data storage media and nanomedicine (diagnostics, biosensor, and therapeutic agents).
