Problems solved by technology

In this patented technology, it is difficult to achieve good dispersion of graphene by directly dispersing graphene oxide into diamine organic matter
At the same time, under the reaction conditions of 100-200°C recorded in the specification, only the effect of "stitching" can be realized, and it is impossible to remove a large amount of oxygen-containing groups of graphene oxide to obtain graphene
Therefore, this patent cannot actually obtain graphene film products

Abstract

The invention provides graphene oxide slurry with interlayers bonded with diamine organic matters and a preparation method of the graphene oxide slurry, and a graphene oxide film with interlayers bonded with diamine organic matters and a preparation method of the graphene oxide film. The preparation method of the graphene oxide slurry with the interlayer bonded diamine organic matter comprises the following steps: adding a diamine organic matter aqueous solution into a graphene oxide aqueous dispersion, and dispersing.

Description

technical field [0001] The invention relates to a preparation process for modifying graphene oxide slurry with diamine substances, and belongs to the field of material synthesis and application. Background technique [0002] Graphene is a two-dimensional nanomaterial structure consisting of only carbon atoms in a hexagonal honeycomb lattice. Since its discovery, it has attracted extensive attention and research due to its excellent mechanical, optical, electrical and thermal properties. Graphene oxide is the oxide corresponding to graphene, which is connected with oxygen-containing functional groups such as hydroxyl, carboxyl, carbonyl and epoxy groups on the graphene sheet. Because the graphene oxide sheet contains a large number of functional groups, the graphene oxide sheet can be self-assembled and stacked through hydrogen bonding to form a macro-sized membrane material. [0003] However, in the process of industrially preparing the graphene thermal conductive film, gr...
