摘要
Abstract
PHA/HA composites were prepared by blending methods with polyhydroxyalkanoates and hydroxyapatite(HA).The effect of the HA content on the crystal and mechanical properties of PHA/HAcomposites were studied.The results show that the Tm and △Hm of PHA/HA composite increases first and then decreases with the increase of HA,and the addition of HA has obvious nucleating effect on PHA/HA composites.PHA/HA composite is a typical ductile material its fracture strength increases first and then decreases with the increase of the amount of HA,and the maximum value is reached when the amount is 15％.The elongation at break and the breaking work of PHA/HA composites first decrease and then increase with the increase of HA content.The impact strength (toughness) of PHA/HA composites decreases first and then increases with the increase of HA content.关键词
