Abstract

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
