• P(MMA-AA-DVB)/Fe3O4 magnetic Janus nanoparticles were synthesized using a solvothermal process.
• Fe3O4 grew preferentially on one side of the polymeric precursor nanoparticle surface.
• Particle size was controlled to be 200 nm by adjusting amount of cross-linker in polymerization.
• Janus nanoparticles were superparamagnetic with a saturation magnetization of less than 25 emu/g.
Inorganic/organic poly(methylmethacrylate-acrylic acid-divinylbenzene) iron oxide Janus magnetic nanoparticles (P(MMA-AA-DVB)/Fe3O4) with strong magnetic domains and unique surface functionalities were prepared using a solvothermal process. The P(MMA-AA-DVB) nanoparticles were prepared via soap-free emulsion polymerization and used as a precursor for preparing Janus nanoparticles. The morphology and magnetic properties of the magnetic Janus nanoparticles formed were characterized using a laser particle size analyzer, transmission electron microscopy, Fourier transform infrared spectroscopy, vibrating sample magnetometry, and thermogravimetric analysis. The synthesized P(MMA-AA-DVB)/Fe3O4 magnetic Janus nanoparticles were characterized by a Janus structure and possessed a stable asymmetric morphology after being dually functionalized. The particle size, magnetic content, and magnetic domain of the P(MMA-AA-DVB)/Fe3O4 magnetic Janus nanoparticles were 200 nm, 40%, and 25 emu/g, respectively. The formation mechanism of the Janus nanoparticles was also investigated, and the results revealed that the reduction of Fe3+ ions and growth of Fe3O4 took place on the surface of the P(MMA-AA-DVB) polymeric precursor particles. The size of the Janus particles could be controlled by narrowing the size distribution of the P(MMA-AA-DVB) precursor nanoparticles.
