專利摘要(英)
A highly compressible shape memory double network hydrogel includes a first network and a second network interlaced each other. The first network is chemically cross-linked cellulose, and the chemical crosslinking is accomplished by the formation of ether groups between the celluloses. The second network is a physically cross-linked alginate, and the physical crosslinking is accomplished by reaction of the alginate with divalent metal ions. In the preparation process of the high compressible shape memory double network hydrogel, the cellulose and the alginate are mixed first, the chemical crosslinking is then performed to obtain the first network, followed by the physical crosslinking to obtain the second network.
