CARBON NANOTUBE SOLUBILIZER

摘要

A hyperbranched polymer containing, for example, a triarylamine structure represented by the formulae (10)-(13) below as a repeating unit, and having a weight average molecular weight of 750-4,000,000 is excellent in dissolving power to carbon nanotubes. Consequently, by using such a hyperbranched polymer as a solubilizer, there can be obtained a composition wherein isolated carbon nanotubes are dissolved.
