| titleOfInvention | Environment-friendly physical crosslinking self-lubricating hydrogel and preparation method thereof |
| abstract | The invention discloses a self-lubricating hydrogel with physical crosslinking and a preparation method thereof, and the preparation method comprises the following steps: mixing water and a water-retaining agent to obtain a mixed solvent; heating the mixed solvent, adding polyvinyl alcohol and a surfactant, and stirring for dissolving to obtain a polyvinyl alcohol/surfactant mixed solution; pouring the mixed solution into a mould, performing circulating freezing melting molding, demolding, soaking in water until the hydrogel is in a stable equilibrium state, and replacing water for multiple times during the period to obtain the environment-friendly polyvinyl alcohol physical crosslinking self-lubricating hydrogel. The raw materials adopted by the invention have no biotoxicity, the cost is low, the reaction condition is mild, the process is safe and simple, and the environment-friendly requirement is met. The surfactant is introduced into the physically crosslinked polyvinyl alcohol hydrogel, and the hydrophobic part of the surfactant is exposed on the surface of the polyvinyl alcohol hydrogel, so that the surface tension of the gel is reduced, the friction force of the gel is reduced, and the product is favorably applied to the artificial articular cartilage replacement material. |
