针对传统水凝胶的复杂制备方法及样品综合性能不佳等问题,以纳米Fe_3O_4和聚丙烯酸为原料,利用仿生矿化法制备了磁响应自修复水凝胶。通过SEM、FT - IR、XRD、TG、磁性测量系统、旋转流变仪对所制备水凝胶的形貌结构及性能进行表征。结果表明,制得的水凝胶结构均匀,对磁场响应灵敏,自修复时间短且可反复自修复,水凝胶的磁性能和流变性能可通过调节纳米Fe_3O_4的添加量来调控。 |

Traditional preparation methods of hydrogel is complicated and the product samples have poor comprehensive performance. Biomimetic mineralization process is used to prepare magnetic response self-healing hydrogel from nano-Fe_3O_4 and polyacrylic acid. The structure and properties of the prepared hydrogel are characterized by scanning electron microscope,Fourier transform infrared spectroscopy,X-ray diffraction,magnetic property measurement system and rheometer. The results show that the as-prepared hydrogel has a uniform structure, is sensitive to external magnetic fields, and can self-heal repeatedly within a short time about 5 minutes. The magnetic property and rheology of the hydrogel can be regulated by adjusting the adding amount of nano-Fe_3O_4 . |
