Carbon nanotube composite dispersant and carbon nanotube dispersion

The invention discloses a carbon nano tube composite dispersing agent and a carbon nano tube dispersoid, the carbon nano tube composite dispersing agent is composed of an anionic dispersing agent and a cationic dispersing agent, the anionic dispersing agent is a small molecule substance containing aromatic ring anions, and the cationic dispersing agent is a cationic water-soluble polymer. The invention also discloses a carbon nanotube dispersion obtained based on the dispersion of the carbon nanotube composite dispersant. According to the composite dispersing agent, the carbon nanotube dispersion obtained by dispersing under the strong electrostatic attraction action between anions and cations has the advantages of few defects, small particles and good conductivity, and is environment-friendly and good in stability. The composite dispersant is obtained by compounding common dispersants, and has an obvious cost advantage. 本发明公开了一种碳纳米管复合分散剂和碳纳米管分散体，所述碳纳米管复合分散剂由阴离子分散剂和阳离子分散剂组成，其中，所述阴离子分散剂为含有芳香环阴离子小分子物质，所述阳离子分散剂为
