▎ 摘　　要

NOVELTY - Selecting graphene filler, comprises (a) preparing complex solution by mixing graphene and glycerol, (b) obtaining a complex viscosity (Pa.s) in graph according to the frequency of the complex solution, and (c) analyzing the graph to determine graphene as a filler. USE - The method is useful for selecting graphene filler. ADVANTAGE - The filler has excellent performance. The method changes in rheological properties of composite of grapheme, and is simple.
