摘　　要：以PVA为骨架材料,戊二醛为交联剂,盐酸为催化剂,通过乳化-化学交联法,在W/O型的乳状液中制备了磁性高分子微球——Fe3O4/交联PVA复合微球。并用SEM,光学显微镜,TG等技术对微球进行表征,考察了不同的盐酸加入方式对微球形貌的影响。Fe3O4/cross-linked PVA composite microspheres were synthesized by the cross linking reaction of polyvinyl alcohol and glutaraldehyde in the W/O emulsion using HCl as a catalyst. The shape of microspheres were characterized by SEM, light microscope and TG. The influence of adding hydrochloric acid way on the shape of microspheres was investigated.
