The present application belongs to the technical field of polymer materials, and relates to a hydrogel material and a preparation method and application thereof. The hydrogel material includes a component A and a component B, and the component A is polyimide; The B component is polyvinylpyrrolidone or polyisopropylacrylamide, and the molecular chains of the A component and the B component are entangled to form a three-dimensional cross-linked network structure, wherein 0<C A <1, C A is the mass fraction of the A component. The hydrogel material provided by this application has both good mechanical properties and swelling properties. When the mass fraction of component A changes, the mechanical properties and water-absorbing swelling properties of the material can be adjusted in a wide range, which can meet the requirements of biological tissues such as cartilage. The requirements for mechanical properties and swelling properties can be used to prepare artificial cartilage. |
