What is it about?
It is clearly shown in experimental test and biphasic finite element analysis for poly(vinyl alcohol) (PVA) hydrogel against glass plate in reciprocating motion that PVA hybrid gel with layered structure as cast-drying (CD) gel on freeze-thawing (FT) gel exhibits extremely low friction and minimal wear.

Why is it important?
Biocompatible PVA hybrid gel with layered structure could be prepared by combination of physically cross-linked FT gel and CD gel at optimum procedure. This hybrid gel as CD on FT shows superior tribological properties as lower friction and lower wear than natural articular cartilage in reciprocating test in saline. The experimental frictional behavior was explained by biphasic finite element analysis.
Perspectives
This article is one of valuable achievements by collaboration with coauthors from mechanical engineering, tribology and material sciences. This article is expected to contribute to clinical application of artificial cartilage in collaboration with orthopedic surgeons.
