▎ 摘　　要

NOVELTY - Solution comprises graphene oxide solution and carbon nanotubes at mass ratio (1-10):1. USE - Used as solution. ADVANTAGE - The solution: has good dispersion effect and easy secondary agglomeration; avoids the damage of the carbon nanotube structure; and improves the mechanical properties of the matrix material. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing solution, comprising (i) preparing graphene oxide solution by controlling the amount of water added in the oxidation by using a modified Hummers method; (ii) adding carbon nanotubes into a container, adding specific amount of graphene oxide solution, and alcohol to dilute to obtain a suspension of graphene oxide and carbon nanotubes; and (iii) dispersing the suspension of graphene oxide and carbon nanotubes ultrasonically using ultrasonic agitator.
