摘要

Single-wall nanotubes {SWNTs) are lightly bundled as a result of strong van der Waals interactions, which constitute the current bottleneck to their application. Few techniques for dispersing and exfoliating as-produced SWNT powder in organic, aqueous polysaccharide, and surfactant solutions have been developed. The use of these exfoliated nanotubes as a polymer filler offers an important advantage over conventional fillers: the extremely high aspect ratio of the SWNT implies that low loading of the NT is sufficient to change a desired property (e.g., conductivity) without sacrificing other inherent properties of the polymer. They could be applied in, e.g., electromagnetic interference shielding or in the fabrication of nanoelectronic devices such as thin-film transistors.
