Abstract Hydrophobic apatite monolith nanoparticles were prepared by grafting of dodecylphosphate (DP) onto hydroxyapatite. A modification in the synthesis was used to develop a hydrophobic surface in order to improve the dispersion and compatibility of organoapatite particles for the sensing and separation of hydrophobic substances. Results indicate that DP grafting onto the apatite is quantitative. Structural analyses of the as-received materials show that the grafting approach did not significantly alter the apatite microstructure, but modifies the hydrophobic character and surface properties of the hybrid material. Conversion of the hydrophilic surface of hydroxyapatite to hydrophobic was carried out to better retain naphthalene as a polynuclear aromatic hydrocarbon model.

羟基磷灰石纳米颗粒的疏水化学表面功能化去除萘

摘要 通过将十二烷基磷酸酯 (DP) 接枝到羟基磷灰石上，制备了疏水性磷灰石整体纳米粒子。合成中的修饰用于开发疏水表面，以改善有机磷灰石颗粒的分散性和相容性，用于疏水物质的传感和分离。结果表明，DP 接枝到磷灰石上是定量的。对原样材料的结构分析表明，接枝方法没有显着改变磷灰石的微观结构，但改变了混合材料的疏水特性和表面特性。将羟基磷灰石的亲水表面转化为疏水表面以更好地保留萘作为多核芳烃模型。
