Starch-g-PVA/hydroxyapatite complex hydrogel was prepared with two-repeated freezing/thawing circles. SEM observation results exhibits that hydroxyapatite is dispersed in starch-g-PVA in nanoscale. Thermogravimetric analysis curves show that the remained fraction keeps the same at the temperatures higher than 490 ℃. It was found the dried starch-g-PVA/hydroxyapatite films could reswell within 12 minutes.
