摘　　要：采用戊二醛作为交联剂,将磁性Fe3O4纳米粒子引入壳聚糖水凝胶中,制得磁性壳聚糖水凝胶。并采用傅里叶变换红外光谱仪、X射线衍射仪和同步差热-热重分析仪对制得的磁性壳聚糖水凝胶进行表征,结果表明,成功制备出了磁性壳聚糖水凝胶。Magnetic chitosan hydrogel was prepared using glutaraldehyde as crosslinking agent, in the presence of magnetic Fe3O4 nanoparticles and chilosan. The as-prepared magnetic chitosan hydrogel was characterized by Fourier Transform Infrared Spectrometer （FT-1R）, X-ray Diffraction （XRD） and Simultaneous TG-DSC. It indicated that magnetic chitosan hydrogel was successfully prepared.
