中文摘要：
通过TEM、FTIR及XRD等检测手段对原位合成法制备羟基磷灰石／碳纳米管复合材料过程中碳管的表面改性及影响羟基磷灰石包覆的因素进行了系统探讨．研究表明，浓酸处理后，碳纳米管表面产生大量官能团；阴离子表面活性剂十二烷基磺酸钠（SDS）的加入提高了碳纳米管与水的相容性；实验中随着（NH4）2HPO04溶液的加入，羟基磷灰石原位沉积并形成包覆层．结果发现；碳纳米管的表面改性、适当的pH值和陈化温度是得到羟基磷灰石连续包覆层的关键因素．
英文摘要：
In order to study the influence of surface modification and other factors on the hydroxyapatite （HAp） coating of carbon nanotubes by an in situ method, the structure of HAp/carbon nanotubes （CNTs） was investigated by means of TEM, FTIR and XRD. Results show that many functional groups are produced on the surface of CNTs by the acid treatment. Using anionic sodium dodecyl sulfate （SDS） as dispersant, the surface properties of CNTs can be changed to yield a basic or acidic surfaces. With the addition of （NH4）2HPO4 solution, HAp is deposited and successfully coated on CNTs. The results also indicate that the surface modification, to obtain continuous HAP layer. proper pH and aging temperature are the key factors
