用聚丙烯酰胺(PAM)对用微乳液法合成的纳米羟基磷灰石(HA)粉体进行有机改性制备。通过用X射线衍射(XRD)、扫描电镜(SEM)、傅立叶转换红外光谱(FT-IR)等测试手段对合成的粉体的化学组分、粒度大小、表面形态进行表征分析。实验结果表明,PAM使 HA 晶体发生相转变,有 CaHPO4的生成。PAM 改性后 HA 杆状颗粒由80 nm 变为120 nm。1635.6 cm-1特征峰表明 PAM与 HA 中的Ca2+发生络合,使PAM接枝在HA表面。另外,探讨了不同质量分数的 PAM-HA 改性粉体水中分散性及吸附重金属离子(Cu2+)性能研究。

Hydroxyapatite nanoparticles were synthesized via a W/O process with Ca(NO3 )2 ·4H2 O and H3 PO4 as raw material.PAM-HA particles were obtained by PAM modification HA in water solution.The morpholo-gy,size,phase structure and FT-IR spectrum of HA and PAM-HA were characterized by transmission electron microscopy,X-ray diffraction,FT-IR spectrograph.The experimental results showed that PAM played a role in crystal transformed of HA,CaHPO4 crystalline phase appeared.The size of PAM modified rod-shaped HA particles were from 80 to 120 nm.Characteristic peak in the 1 635.6 cm-1 showed that PAM and Ca2 + in the HA complexation,PAM grafted on the surface of HA.In addition,the dispersion and adsorption performance (Cu2 +)of PAM-HA were improved.
