Abstract: 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-Fe3O4 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-Fe3O4.
