【摘要】 采用浓酸对多壁碳纳米管进行氧化处理,然后利用表面活性剂十二烷基硫酸钠将碳纳米管分散在水中,之后采用磷/钙液反复浸泡的方法对碳纳米管进行矿化。采用红外光谱、扫描电镜等对氧化处理和表面活性剂分散前后的碳纳米管及所得矿化产物进行了分析。实验结果表明:经过浓硝酸氧化处理,多壁碳纳米管表面引入大量的羟基与羧基,这为进一步矿化的基础;扫面电镜结果表面纳米级的羟基磷灰石均匀沉积于碳纳米管表面,形成了较强的界面结合。更多还原

【Abstract】 The multi-walled carbon nano-tubes(MWNTs)were oxygenated by concentrated acid,and dispersed by adding surface active agent,the mineralized MWNTs were chemically synthesized by using an alternate soaking process.The sam- ple were characterized by infrared spectrum and field emission electron microscopy.The results showed that the MWNTs functionalized with hydroxyl and earboxyl groups form an efficient matrix for the mineralization of HAp crystals.HAp crys- tals were uniformly mineralized on the MWNTs and formed good interfacial bonding at the same time.更多还原
