| titleOfInvention | The preparation method with poly-(NIPA-methacrylic acid) porous microsphere of magnetic field and temperature dual response |
| abstract | The preparation method that the present invention relates to a kind of poly-(NIPA-methacrylic acid) porous microsphere with magnetic responsiveness and temperature sensitivity, first adopt the method that alkali acid progressively processes to prepare the polyalcohol stephanoporate microballoons with temperature sensitivity, then adopt coprecipitation in-situ preparation Fe in the surface and duct of porous microsphere 3 O 4 Nanoparticle. The invention has the beneficial effects as follows: polymerization process " a pot " completes, and last handling process is also simpler. Poly-N-isopropyl acrylamide skeleton is that compound system provides Thermo-sensitive, in the surface and duct of porous polymer microsphere, generated in-situ ferriferrous oxide nano-particle is that polymer microballoon provides good superparamagnetism, and the loose structure in polymer microballoon is its condition provided convenience in biological medicine controlled release and magnetic targeted administration. |
