| 中文摘要 | Uniform magnetic poly(styrene-co-2-hydroxyethyl methacrylate) (PST-HEMA) microspheres were fabricated by a novel route combining premix membrane emulsification of double emulsion and an in situ magnetization technique. The fabrication involved, first, the preparation of uniform double W/O/W emulsions with ferrous ferric solution as the internal water phase and dichloromethane dissolved with PST-HEMA as the oil phase by premix SPG membrane emulsification. Then, the inner ferrous ferric solution was in situ magnetized into nanoparticles by adding the ammonia solution into the external water phase. This W/O/S emulsion was finally solidified into microspores by solvent evaporation. Results showed that the in situ magnetization technique could effectively overcome the encapsulation difficulties in traditional synthesis routes due to poorer affinity between iron oxide nanoparticles and polymer, and facilitated the enhancement of encapsulation efficiency with a high magnetization up to 14.23 emu/g. |
