利用原位合成法获得羟基磷灰石包覆的碳纳米管复合粉体,对制备过程中可能影响羟基磷灰石包覆层效果的因素进行了探索。结果表明:羟基磷灰石可以在阴离子修饰后的多壁碳纳米管上形核结晶;在实验过程中,pH值影响最终产物的组成,而陈化温度和陈化时间对包覆层中羟基磷灰石晶粒的尺寸和厚度有明显影响。 The hydroxyapatite-coated carbon nanotube composite powder was obtained by the in-situ synthesis method, and the factors that may affect the effect of the hydroxyapatite coating during the preparation process were explored. The results showed that hydroxyapatite could nucleate and crystallize on the anion modified multiwalled carbon nanotubes. During the experiment, the pH value affected the composition of the final product, and the aging temperature and aging time had no effect on the hydroxyl groups Apatite grain size and thickness have a significant impact.
