Abstract

Nano-hydroxyaptite/polyvinyl alcohol (n-HA/PVA)composite hydrogels were prepared and the swelling properties of n-HA/PVA were studied. The result showed that the water content, swelling ratio and dissolution ratio of the composite hydrogels were affected by content of n-HA in the hydrogel and freezing-thawing cycles’ time. The water content, swelling ratio and dissolution ratio were inversely proportional to the content of n-HA in the hydrogels, and the water content and dissolution ratio were also inversely proportional to the freezing-thawing cycles’ time, while the swelling ratio increased with the freezing-thawing cycles’time.
