[The development of a kind of artificial articular cartilage-PVA-hydrogel].
In this study, the process included aqueous Poly (vinyl alcohol) solutions frozen at -20 degrees C for 6-12 h, and then thawed for 1-2 h. The same process was repeated 1-3 times. After the specimen was dehydrated in vacuum, a kind of artificial articular cartilage--PVA-hydrogel was made up. Subsequently, the micromorphology of PVA-hydrogel was observed by means of optical microscopy and SEM. DSC and mechanical tests were employed in ivestigating the influence of freesing, thawing, dehydrating and irradiating upon the crystallity and the mechanical properties of PVA-hydrogel.
