▎ 摘　　要

NOVELTY - Detecting storage stability of a graphene-based material dispersion liquid involves performing metallographic detection of graphene-based material dispersion to obtain dispersion state and/or morphology of graphene-based material in the dispersion system. The graphene-based material dispersion liquid is centrifuged to obtain a centrifugal liquid, and then it is detected that there is agglomeration and/or layering at bottom of centrifuge. The centrifugal liquid is stirred, and lower layer of the centrifugal liquid is taken for metallographic inspection to obtain dispersion state and/or morphology of graphene-based material in lower layer of the centrifugal liquid in dispersion system, and then metallographic detection results are compared to determine the storage stability of the graphene-based material dispersion. USE - Method for detecting storage stability of a graphene-based material dispersion liquid. ADVANTAGE - The method enables to detect storage stability of a graphene-based material dispersion liquid, which quickly detects dispersibility of graphene-based material dispersion liquid, and dispersibility and stability after long-term storage through simple centrifugal separation and stirring methods. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for determining storage stability of a graphene-based material dispersion liquid, which involves: (A) obtaining centrifugal liquid after centrifuging and stirring the graphene material dispersion liquid, where centrifugal treatment is performed at speed of 200-1000 revolutions per minute for 30-240 minutes; and (B) taking lower layer of centrifugal liquid for metallographic inspection, and obtaining dispersion state and/or morphology of graphene-based material in lower layer of centrifugal liquid in the dispersion system, where dispersion state and/or morphology of graphene-based material in lower layer of centrifugal liquid in dispersion system is same as dispersion under metallographic detection of lower layer of dispersion after graphene-based material dispersion is stored for 6 months State and/or topography, and is greater than or equal to 90%.
