Bioinspired polymer-incorporating self-lubricating and antifouling hydrogels.
Healthy articular cartilage exhibits a very low coefficient of friction (CoF ≈ 0.002-0.02) due to hydration lubrication at the slip plane, involving phospholipids bound to macromolecules in the cartilage matrix. Hydrogels that mimic this hydrated phosphorylcholine layer could replicate cartilage lubrication for biomedi...
