More Information
Summary:The invention provides a preparation method of a magnetic gel based on ferromagnetic gamma-Fe2O3 nano particles, which is used for forming a ferromagnetic gel in a ferromagnetic sol through an electrolyte. The magnetic gel has the characteristics that the gel does not contain any organic matter and is a semisolid material with ferromagnetism, and the obtained gel can reversibly change between a (semi) solid state and a liquid state and keep magnetism constant.
