| Outline of Final Research Achievements |
The detailed mechanism of adaptive multimode lubrication in natural synovial joints has been elucidated and subsequently those results will be applied to develop innovative artificial cartilage. It was shown that friction and wear properties of hydrogels depend on the types of hydrogels and lubricants. The superior lubrication mechanism of articular cartilage and poly (vinyl alcohol) hydrogels are evaluated from the viewpoint of biphasic and boundary lubrication mechanisms. The PVA hybrid hydrogel artificial cartilage as optimized laminated structure has shown superior lubricity with extremely low friction and minimum wear.
