摘要
以尿素沉淀剂,运用溶液均匀共沉淀法制得纤维状羟基磷灰石(HAP)和无定形颗粒状守壳聚糖(CS)的复合粉体,通过水势处理调整纤维状HAP晶粒尺寸的大小,对粉体进行了XRD、TEM、IR及化学组成(Ca/P)表征。均匀 水热共沉淀过程中,pH值对粉体Ca/P、XRD、TEM。
Using urea as the precipitant,the fibrous hydroxypatite(HAP)/chitosan (CS)composited powder was prepared with homogeneous co-oprecipitation,and the grain size of HAP was adjusted with hydrothermal treating(0.2MPa).The composited powder was characterrised by XRD,TEM and IR and chemical composition(Ca/P).In the course of homogeneous-hydrothermal co-precipitating,the pH value had great influence on Ca/P,XRD,TEM,and IR.
