Abstract

Biocompatibility Compression testing Crosslinking Dehydration Hydrogen bonds Polymer blends Polyvinyl alcohols Stiffness Surgery Volume fraction
The effect of dehydration history on associating hydrogels for nucleus pulposus replacement was examined. The properties of polyvinyl alcohol (PVA) and polyvinyl pyrrolidone (PVP) hydrogel blends were found to be strongly dependent on the material's dehydration history. Partial dehydration/rehydration was found to be a viable process for anthroscopical performance of nucleus pulposus replacement surgery.
