由于它们与骨磷灰石的相似性，磷酸钙生物陶瓷，如羟基磷灰石（HAp），被用作硬组织替代物的生物材料。生物陶瓷和生物医学聚合物的复合材料可以模拟骨的结构和性能。描述了包含HAp和生物医学聚合物并在低温下制备的复合材料的特性。在携带羧酸部分的聚磷腈聚合物（酸-PCPP）的存在下，在25° C至50°C的温度下建立HAp形成的动力学。在存在的固体，溶液化学，和微观结构的发展的组合物的演变被建立为反应时间和温度的函数。聚合物参与HAp形成，通过形成钙交联影响其成核和生长速率。聚合物的存在也增强了延展性。
Owing to their similarities to bone apatite, calcium phosphate bioceramics, such as hydroxyapatite (HAp), are used as biomaterials for hard tissue replacements. Composites of bioceramics and biomedical polymers can mimic bone structure and properties. The characteristics of composites comprising HAp and a biomedical polymer and prepared at low temperatures are described. The kinetics of HAp formation in the presence of a polyphosphazene polymer that carries carboxylic acid moieties (acid-PCPP) were established at temperatures from 25° to 50°C. Evolution in the compositions of the solids present, solution chemistry, and microstructure development were established as functions of reaction time and temperature. The polymer participated in HAp formation affecting its rates of nucleation and growth through the formation of calcium cross links. The presence of polymer also enhanced ductility.
