NOVELTY - The method involves determining a slurry sample from a dividing cylinder. An absorbance value of an initial state slurry is determined according to the slurry sample. A slurry time is calculated. A sedimentation and stability analysis ratio are determined according to a settling parameter. A relation curve of the settling parameter is drawn. A graphene slurry stability representation model is established, where specific wavelength of the absorbance is 400-1000nm. USE - Exosymptom model building graphene slurry stability method. ADVANTAGE - The method enables achieving stability characterization model. DESCRIPTION OF DRAWING(S) - The drawing shows a graph of an exosymptom model building graphene slurry stability method.
