▎ 摘　　要

NOVELTY - Preparation of graphene-containing special liquid involves chemically modifying a graphene material, obtaining a modified graphene material, dispersing a surfactant into a base material in a stirring device, obtaining a liquid mixture, dispersing the modified graphene in the liquid mixture in the stirring device, obtaining a graphene-containing liquid mixture, and processing resultant in an ultrasonic vibrator. USE - Preparation of graphene-containing special liquid used as heat regulation fluid in circulating system of satellite. ADVANTAGE - The method enables preparation of graphene-containing special liquid having high thermal conductivity coefficient, and excellent stability even under extreme temperature environment in space. The circulating system using the graphene-containing special liquid has improved efficiency.
