High-efficiency dispersion and sorting of Single-walled Carbon Nanotubes via non-covalent interactions

Abstract

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, tend to form bundles or entangled ropes owing to high Van der Waals attraction and π-π interactions among inter-tubes. Therefore, the dispersion and sorting of SWCNTs with both high-yield and desirable electronic structures has been a great challenge but a long-term motivation to achieve practical utility since its discovery. This review provides a comprehensive summary of strategies for surface modification and dispersion of SWCNTs, and surveys the up-to-date development of SWCNTs enrichment via mainly non-covalent interactions with molecular species. The effect of molecular architecture of selective dispersion and sorting of SWCNTs by surfactants, bio-macromolecules and conjugated polymers has been discussed with respect to the structure-property relationship and interaction mechanism
