▎ 摘 要
NOVELTY - A high-concentration graphene dispersion comprises 1-7 pts. wt. graphite, 0.01-0.1 pt. wt. graphene aerogel as an anti-settling agent, 0-0.4 pt. wt. dispersing agent and remaining solvent. USE - High-concentration graphene dispersion (claimed). ADVANTAGE - The high-concentration graphene dispersion has excellent stability, high concentration of graphene of 70 mg/ml, and suppressed generation of layered precipitation of dispersion. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of high-concentration graphene dispersion, which involves mixing graphite, graphene aerogel, dispersing agent and solvent, stirring resultant mixture at 300-1000 rpm, adding resultant mixture to a mechanical stripping equipment, peeling, obtaining a graphene dispersion, and filtering or centrifuging resultant product.
