Problems solved by technology

In this case, each particle dispersed in water tends to be in a strongly fixed state, and it is not easy to dissociate into the original particle size. In order to make it into a dispersion, it needs to be processed by bead mill (beads mill) or the like, and there is a place for dispersion. Problems requiring more energy and time

Abstract

Disclosed is an organic solvent dispersion of a conductive polymer / dopant, which is obtained by dispersing a conductive polymer (A) and a dopant (B) in an organic solvent by using a dispersing agent composed of a hydroxylated acrylic polymer having a weight average molecular weight of 10,000-50,000 and a hydroxyl number of 160-230 mgKOH / g. The water content of this organic solvent dispersion is not more than 20% by weight. Also disclosed are a resin composition containing the organic solvent dispersion and a binder, and a coating composition containing such a resin composition.

Description

technical field [0001] The invention relates to an organic solvent dispersion of a conductive polymer / dopant, and a composition containing the organic solvent dispersion. Background technique [0002] Conductive polymers with π-conjugated architecture exhibit good conductivity and stability, so they are used as industrial materials such as various antistatic agents and electrode materials. This conjugated system conductive polymer is given high conductivity by adding a substance called a dopant to exhibit conductivity. For example, in recent years, poly(3,4-ethylenedioxythiophene) (hereinafter sometimes referred to as PEDOT) has been widely used mainly as an antistatic agent. PEDOT is a process in which 3,4-ethylenedioxythiophene as a monomer is prepared by using an oxidizing agent in the presence of polyanions such as polystyrene sulfonic acid (hereinafter sometimes referred to as PSS) as a dopant in an aqueous phase. polymerized and thus obtained in the form of water-sol...
