▎ 摘　　要

NOVELTY - Sulfonic functional graphene dispersing system comprises sulfonic functional graphene, nano-cellulose and organic solvent, where the portion of the nanocellulose composited in the sulfonic acid group. The organic solvent at least serves to uniformly disperse and/or dissolve the remaining components of the dispersion to form a homogeneous dispersion. USE - Used as sulfonic functional graphene dispersing system. ADVANTAGE - The sulfonic functional graphene dispersing system has good stability, not easy to agglomerate and simple preparation method. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing the sulfonic functional graphene dispersing system, comprising (i) dispersing sulfonic functional graphene in the organic solvent to obtain the sulfonic functional graphene dispersion, (ii) adding the nanometre cellulose to step (i) to obtain sulfonic functional graphene dispersion, water bath stirring and ultrasonic dispersing.
