| 摘 要： | 采用静电自组装实现了壳聚糖（CS）对碳微球（CMSs）的包覆。将化学气相沉积法制得的CMSs用HNO3和H2O2混合溶液进行表面氧化修饰,引入含氧官能团,使其表面带负电,通过静电作用力与带正电的CS自组装,从而改变了CMSs的表面活性。利用场发射扫描电子显微镜、傅立叶红外光谱仪、X-射线衍射仪及热重分析仪等检测手段表征了产物的形貌和结构特征。结果表明：CS成功地组装到CMSs表面,当CMSs与CS的质量比为1∶2时,CS均匀覆盖于CMSs表面,而且在水溶液和乙醇中的分散性较好。

| Abstract: | Carbon microspheres (CMSs) covered with chitosan (CS) was performed by electrostatic self-assembly.CMSs,which were synthesized by chemical vapor deposition,were firstly oxidized by a mixture of concentrated HNO3 and H2O2,thus changing the surface activity of CMSs by electrostatic interaction between CMSs with negative charge and CS with positive charge.The morphologies and microstructures of the products were characterized by field emission scanning electron microscopy,Fourier transformation infrared spectr... |
