本文基于聚苯乙烯（PS）和多壁碳纳米管（MWCNT）之间的非共价相互作用，研究了通过溶液混合对多壁碳纳米管（MWCNT）进行分散和改性。研究发现，在剧烈超声处理后，相互作用足以稳定溶液中解束的 MWCNT。所附着的 PS 改变了多壁碳纳米管的表面特性，使它们易于溶于有机溶剂，即使在用溶剂仔细清洗后也能保留下来。此外，许多其他基于PS的聚合物被证明保留了分散MWCNT以形成稳定溶液的能力。 © 2008 Wiley periodicals, Inc. J Appl Polym Sci，2008
This article investigated the dispersion and modification of multiwalled carbon nanotubes (MWCNTs) through solution mixing based on the noncovalent interactions between polystyrene (PS) and MWCNTs. It was found that the interactions were robust enough to stabilize the debundled MWCNTs in solution after vigorous sonication. The PS attached, which altered the surface properties of MWCNTs and made them easily soluble in organic solvents, can remain even after careful washing with solvents. Besides, many other PS-based polymers were proved to retain the ability to disperse MWCNTs to form stable solutions. © 2008 Wiley Periodicals, Inc. J Appl Polym Sci, 2008
