Research Progress in Magnetic Hydrogels

Hydrogels are hydrophilic but can't bedissolved in water,and a kind of cross-linked polymers with structure of three-dimensional network.They have been of great interest to materials science and biomaterial fields because of the unique hydrophilicitg and good biocompatibility.Hydrogels have been extensively applied and researched.In this paper the research of hydrogels in the fields of biomedical applications is reviewed according to the radiation synthesis of magnetic hydrogels in laboratory.The preparation and the application of magnetic hydrogels are introduced emphatically,and its development is prospected.
