用原位合成法成功制备出多壁碳纳米管/羟基磷灰石[multi-walled carbon nanotube(MWNT)/hydroxyapatite(HA)]复合材料,并对其进行了多种检测。红外分析结果显示:经过浓硝酸回流处理后,MWNT表面产生大量阴离子官能团,这是后期HA形核长大的基础。X射线衍射结果表明:适当的pH值是合成HA的关键因素。透射电镜照片显示:pH值为10时,HA在MWNT表面形核结晶;HA颗粒的尺寸与陈化温度成正比。 Multi-walled carbon nanotubes (MWNTs) / hydroxyapatite (HA) composites were prepared successfully by in-situ synthesis method and tested. Infrared analysis results show that after concentrated nitric acid refluxing, a large amount of anionic functional groups are formed on the surface of MWNTs, which is the basis for the growth of HA nuclei in the later stage. X-ray diffraction results show that: the appropriate pH value is the key factor in the synthesis of HA. Transmission electron micrographs showed that HA crystallized on the surface of MWNTs at a pH of 10, and HA particles were proportional to the aging temperature.
