Preparation method of agar-based self-healing biomimetic low-friction hydrogel articular cartilage |
| abstract |
The invention discloses a preparation method of an agar-based self-repairing bionic low-friction hydrogel articular cartilage. The method adopts agar hydrogel as a physical cross-linked network, and polyacrylic acid-polyacrylamide hydrogel as a chemical cross-linked network to form a double-layer network structure, and introduces iron ions to form coordination with polyacrylic acid to prepare a Hydrogels with porous aqueous structures. The invention uses the dynamic and reversible ion coordination bonds and hydrogen bonds between the networks to endow the agar/polyacrylic acid-polyacrylamide-iron ion double network hydrogel with higher self-repair ability and mechanical properties. Compared with pure agar hydrogel, the agar/polyacrylic acid-polyacrylamide-iron ion double network self-repairing hydrogel articular cartilage of the present invention has a compression modulus increased by 80% to 120%, and better self-repair is achieved performance. |
