摘要
以异丙胺为原料,先合成出了异丙胺-N,N-二甲基双磷酸酯,以异丙胺-N,N-二甲基双磷酸酯为空间位阻剂,采用共沉淀法合成了内核为无定形纳米磷酸钙(ACP),壳层为异丙胺基团的纳米杂化材料.用激光粒度分析(LPSA)和傅里叶变换红外光谱(FTIR)对材料结构进行了表征.结果表明,所合成的杂化材料能在水中以纳米级稳定存在.
Using isopropyl amine as main raw material, isopropyl amine-N, N-dimethyl double phosphate is synthesized firstly, which then serves as space steric hindrance agent in the synthesis of nanohybrid material through the method of coprecipitation, whose kernel is amorphous nano calcium phosphate （ACP） and isopropyl amine group of nanohybrid materia is the shell. Fourier transform infrared spectroscopy （FTIR） and laser particle size analysis （LPSA） are used to characterize the structure of the material, and the result shows that the synthesized hybrid material exists stably in the water in nanoscale.
