This article presents the synthesis of poly(methacrylic acid)‐ b ‐poly(methyl methacrylate) diblock copolymer via polymerization‐induced self‐assembly in the presence of iron‐oxide nanoparticles. Detailed phase diagrams with and without inorganic nanoparticles were constructed. Scanning transmission electron microscopy and energy dispersive X‐ray photometry studies confirme the decoration of the polymeric nanoparticles with the iron‐oxide nanoparticles. These hybrid nanoparticles were used to prepare porous thin film membranes by spin coating. Finally, the magneto‐responsive properties of the membranes were assessed using water filtration tests in the presence and absence of a magnetic field.
