Single-walled carbon nanotubes (SWCNTs) have attracted great attention on account of their superior and tunable electrical properties for promising applications in low-cost and high-performance nano-electronics and thin-film devices. However, SWCNTs are usually produced as a mixture of m-/s-nanotubes with small diameters and long aspect ratios and tend to form bundles or entangled ropes owing to their high van der Waals attraction and π–π interactions among their inter-tubes. Therefore, the dispersion and sorting of SWCNTs with both a high yield and desirable electronic structures has been a great challenge but a long-term motivation to achieve greater practical utility of SWCNTs. This review provides a comprehensive summary of the strategies for the surface modification and dispersion of SWCNTs, and surveys progress on the up-to-date development of SWCNTs enrichment via mainly non-covalent interactions with molecular species. The effect of the molecular architecture on the selective dispersion and sorting of SWCNTs by surfactants, bio-macromolecules, and conjugated polymers is discussed with respect to the structure–property relationship and interaction mechanism.

通过非共价相互作用对单壁碳纳米管进行高效分散和分选

单壁碳纳米管（SWCNT）由于其优越的和可调节的电性能而备受关注，可用于低成本，高性能的纳米电子和薄膜设备中。但是，SWCNT通常以小直径和长径比的m- / s纳米管的混合物形式生产，由于其高范德华吸引力和管间的π-π相互作用，往往会形成束或缠结的绳索。因此，具有高产率和期望的电子结构的SWCNT的分散和分选一直是巨大的挑战，但是长期的动机是实现更大的SWCNT的实用性。这篇综述全面概述了SWCNT的表面改性和分散策略，主要通过与分子种类的非共价相互作用。讨论了分子结构对表面活性剂，生物大分子和共轭聚合物对SWCNTs选择性分散和分选的影响，并探讨了结构，性质之间的关系和相互作用机理。
