CARBON NANOTUBE DISPERSION

摘要

A carbon nanotube dispersion, and a method for preparing a transparent electrode by using the dispersion are provided to improve dispersion stability of a carbon nanotube and to allow it to be dispersible in aqueous/organic phase. A carbon nanotube dispersion comprises 0.001-0.05 parts by weight of a carbon nanotube; 100 parts by weight of a solvent; and 0.01-0.3 parts by weight of a multifunctional ethylene oxide-propylene oxide block copolymer as a dispersant. Preferably the multifunctional ethylene oxide-propylene oxide block copolymer is a tetrafunctional ethylene oxide-propylene oxide block copolymer represented by the formula 3 or 4, wherein A is an ethylene oxide repeating unit or a propylene oxide repeating unit; m, n and x are an integer satisfying m+n+x>10; and y is an integer satisfying 1
