Abstract

To know the effect of hydrating water on the mechanical property of cartilage, we carried out dielectric and viscoelastic measurements to chondroitin sulfate. In the dielectric measurements of CS aqueous solutions, it became clear that around CS there was hyper mobile water whose rotational mobility is higher than that of free water. And in the viscoelastic measurements of CS hydrogels whose number of hyper mobile water was decreased by addition of NaCl to solution, we could see that the viscosity of CS gel decreased when its NaCl concentration was changed from 0.001M to 0.01M.
