| 摘 要： | 以聚乙二醇单甲醚(MPEG)为原料, 采用先磷酰化再水解的方法合成了聚乙二醇单甲醚磷酸酯(P-MPEG). 以P-MPEG为空间位阻剂, 采用共沉淀法合成了内核为纳米羟基磷灰石(nHA)、 壳层为MPEG链的纳米杂化材料. 用傅里叶变换红外光谱(FTIR)、 X射线衍射(XRD)、 透射电子显微镜(TEM)和激光粒度分析(LPSA)对材料结构进行了表征. 结果表明, 所合成的杂化材料不仅能在水中再分散, 而且可以在甲醇和二甲基甲酰胺(DMF)等有机溶剂中再分散.

| Abstract: | Poly(ethylene glycol ether) phosphate(P-MPEG) was synthesized through phosphorylating and hydrolyzing using poly(ethylene glycol methyl ether)(MPEG) as raw material.Then hybrid material with nHA core and polymer shell was synthesized through precipitation with P-MPEG as the steric hindrance agent.The nHA was characterized by Fourier transform infrared spectroscopy(FTIR),X-ray diffraction(XRD),transmission electron microscopy(TEM) and laser particle size analyzer(LPSA).The synthesized hybrid material is redispersible not only in water,but also in organic solvents such as methanol,N,N-dimethylformamide(DMF),etc.Feasibility of nHA with excellent redispersible ability using organic phosphate as the steric hindrance agent was confirmed. |
