Interfacially active and magnetically responsive composite nanoparticles with raspberry like structure; synthesis and its applications for heavy crude oil/water separation

- P(MMA-AA-DVB)/Fe3O4 Magnetic composite nanoparticles in micro scale were prepared by solvothermal process.
- P(MMA-AA-DVB)/Fe3O4 effectively attached to the stable emulsified water droplets in emulsion.
- The obtained composite nanoparticles expressed excellent recycling property for separation of water in crude oil emulsion.
- The recycled P(MMA-AA-DVB)/Fe3O4 retained its interfacial activity, surface morphology after demulsificetion.
