▎ 摘  要

NOVELTY - The method involves performing the strain on the graphene oxide suspension liquid by using a strain-controlled rotary shear rheometer to obtain a storage modulus and a loss modulus. A specific strain rate is selected from the modulus-strain curve chart as a strain level fixed by frequency scanning. The frequency scanning is performed on the strain value selected to obtain a storage modulus and a loss modulus in a balanced state. A flow steady state scanning experiment is performed to obtain stresses at different shear rates. A curve graph is drawn by taking the shear rate as an abscissa and the stress as an ordinate. The nonlinear rheological phenomenon and mechanism of the graphene oxide suspension are obtained with the linear elastic aging property according to the curve chart. USE - Rheology measuring method of viscoelastic aging property of graphene oxide suspension. ADVANTAGE - The method is good for determining the graphene oxide fluid property, the nonlinear behavior analysis under the flow field has a certain help, and it has certain guiding meaning for solving the problem of graphene oxide suspension solution method processing technique process. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the atomic force microscopy (AFM) image of graphene oxide.
