摘　　要：采用导向沉淀法在胺化的P(AA/MMA/GMA)@Fe3O4(MCM,其中AA为丙烯酸,MMA为甲基丙烯酸甲酯,GMA为甲基丙烯酸缩水甘油酯)微球表面负载ZnO粒子制备得到了ZnO@P(AA/MMA/GMA)@Fe3O4(ZPM)三层结构磁性复合微球。通过XRD、SEM、粒度分析、TGA及VSM等手段对ZPM微球进行表征,结果表明:ZPM微球平均粒径为1.38μm,ZnO负载量为13.02%,比饱和磁化强度为8.64 emu.g-1。同时研究了ZPM微球的光催化性能,以罗丹明B(RhB)为被降解物,微球对RhB的吸附效率为50.07%,催化降解效率可达93.40%。ZnO particles were loaded on the surface of aminated P（AA/MMA/GMA）@Fe3O4 composite microspheres（MCM,AA： acrylic acid,MMA was methyl methacrylate,GMA： glycidyl methacrylate） for preparing ZnO@P（AA/MMA/GMA）@Fe3O4（ZPM） with three-layer structure by guided deposition.The structure and properties of ZPM were analyzed by XRD,SEM,Laser Particle Size Analyzer,TGA and Vibrating Sample Magnetometer（VSM）.The results show that the ZPM microspheres are with perfect sphere-shaped morphologies with a saturation magnetization of 8.64 emu·g-1.The average particle size of ZPM microspheres is 1.38 μm and content of ZnO is 13.02%.Photocatalysis of ZPM microspheres was studied using degradation of RhB as a model reaction.Adsorption and degradation efficiency of ZPM are 50.07% and 93.40%.
