摘要:

利用银溶胶活化诱导淀粉螺旋结构实现了多壁碳纳米管非共价表面修饰. 实验结果表明, 淀粉非共价表面修饰的多壁碳纳米管在水中容易分散, 扫描电镜分析表明, 经银溶胶处理的多壁碳纳米管被单根分散在银溶胶溶液中. 酶解试验、IR和EDS分析表明, 碳纳米管表面修饰了一层淀粉.

Abstract:

A facile noncovalent surface modification method for multi-walled carbon nanotubes(MWNTs) through soluble starch to be prearranged helical state produced by complexing with silver colloid was described. The starch modified MWNTs show great ease of exfoliation into water and SEM analysis shows a significant debundling upon silver colloid treatment. Amylatic reaction, IR and EDS analysis indicate the MWNTs surface modification by soluble starch.

Key words: Soluble starch; Silver colloid; Multi-walled carbon nanotubes; Noncovalent surface modification
