| 摘 要： | 通过聚醚酰亚胺修饰得到了氨基化的多壁碳纳米管,并采用傅里叶变换红外光谱、透射电镜、拉曼光谱和热重分析对产物进行表征。通过估算,平均每根383 nm长的多壁碳纳米管接枝上了1 200个聚醚酰亚胺分子,约含一级胺的数目为28万个,即平均每100个碳原子接上了1.8个一级胺,大大增加了多壁碳纳米管表面的氨基数量。此外,修饰后的碳纳米管的溶解度显著提高,约2 mg/mL,利于进一步开发其在生物传感器、药物载带、组织工程、生物显像等生物医药领域的应用。

| Abstract: | Multi-walled carbon nanotubes(MWCNTs) were functionalized with polyethyleneimine(PEI),thus introducting a plenty of amino groups onto their surface.The product was fully characterized by fourier transform infrared spectroscopy,transmission electron microscopy,Raman spectroscopy analysis and thermogravimetric analysis(TGA).TGA analysis shows the PEI-grafting rate was 17.5%.It is estimated that,each PEI-MWCNT(ca 383 nm long) was grafted with 1200 PEI molecules,containing about 280 thousand amines,which means ... |
