基于溶液法的单壁碳纳米管手性分离

Chiral-separation of single-walled carbon nanotubes in the solution

本文综述了基于溶液法分离策略,利用表面活性剂、生物分子、共轭聚合物分子在溶液中分散或选择性分散单壁碳纳米管(SWCNTs),结合各种分离技术获得单一手性SWCNTs的研究进展.阐述了不同体系中SWCNTs手性分离的原理,综合比较了不同分离技术的优缺点.单一手性SWCNTs分离技术的不断进展有助于推动单壁碳纳米管的进一步研究与应用.

Based on the solution separation strategy, we reviewed the recent progress in the approach that single-walled carbon nanotubes （SWCNTs） are dispersed or selectively dispersed by surfactants, biomolecular or conjugated polymers in solution, and then sorted out with several separation techniques to obtain single-chirality SWCNTs. We demonstrated the separation mechanism of SWCNTs by the different systems and gave a comprehensive evaluation with these techniques. Sustained progress in the separation techniques of single-chirality SWCNTs will greatly promote the further research and application of SWCNTs.
