The invention relates to a preparation method of high-strength
ion-responsive lubricating hydrogel, belonging to the technical field of
ion response. The preparation method combines a high-strength hydrogel material with a synergistic design
system of
ion-responsive supramolecular hydrogel, and realizes the regulation and control of the surface
lubrication of the hydrogel material by regulating the bulk phase of the hydrogel material as well as surface ion species and charged state. On the one hand, the high-strength hydrogel can give good mechanical support to
cartilage; on the other hand, the ion-responsive supramolecular hydrogel can undergo gel-
sol conversion under the action of external ions, and the factors such as ion species and concentration of the environment in which the hydrogel is located can be further controlled according to
complexion situations of different ions by an ion-
responsive polymer, so that the purpose of reversible regulation of hydrogel surface
lubrication is achieved, and the hydrogel is enabled to automatically adjust the strength and the surface
lubrication performance. The high-strength ion-responsive lubricating hydrogel greatly enhances the stability and environmental adaptability of bionic
cartilage, thus having a very good medical prospect.
