摘要
利用自由基引发原位聚合的方法合成了聚乙烯基吡咯烷酮 (PVP)包裹的碳纳米管 (Nanotubes NT) ,并利用TGA ,UV Vis ,Fluorescence和TEM等对产物进行了表征 .结果表明 ,碳纳米管可以利用自由基引发 ,通过原位聚合过程与乙烯基吡咯烷酮发生反应 .产物NT PVP室温下能溶于水及甲醇、氯仿、二硫化碳等各种普通的有机溶剂 ,从而为碳纳米管进一步的深入研究和应用消除了障碍 ,开辟了广阔的前景 .
A carbon nanotube wrapped by polyvinyl pyrrolidone (NT PVP) was synthesized by in situ polymerization of vinyl pyrrolidone initiated by free radical in the presence of the nanotube. UV Vis, fluorescence, TEM and TGA were employed to characterize the NT PVP polymer obtained. It was found that the nanotube in the NT PVP is thickly and helically wrapped by the PVP chains. This product can easily be resolved in common solvents such as water, methanol, chloroform, carbon bisulfide and other organic solvents.
