Abstract

The invention discloses a method for synchronously reducing and modifying graphene oxide, and particularly relates to a method for preparing graphene containing a large number of long carbon chains on the surface as well as polymerizable carbon-carbon double bonds and showing good dispersibility in an organic solvent through chemical reduction by taking the extraction liquid urushiol of the Chinese lacquer tree or the extraction liquid cardanol of cashew nut shell as a reducing agent and a modifying agent without adding any stabilizer or dispersant, which provides convenience to the follow-up preparation of a graphene-based polymer composite. The method disclosed by the invention is green and environment-friendly, simple in process, low in production cost and easy to popularize and use; the reaction process is easy to control; and particularly, the surface-modified unsaturated urushiol or cardanol with a long side carbon chain can be crosslinked or blended with most polymers, thereby being favorable for applying the modified graphene to the field of new materials such as high-molecular composites.

Description

technical field

[0001] The invention relates to a method for simultaneously chemically reducing and modifying graphene oxide, in particular to a method for reducing and modifying graphene oxide by utilizing natural green compounds urushiol or cardanol to prepare a surface containing a large number of long carbon chains and the presence of polymerizable carbon The carbon double bond and the method for graphene with good dispersibility in an organic solvent provide convenience for the subsequent preparation of graphene-based polymer composite materials, and belong to the field of nanomaterials. Background technique

[0002] When the two-dimensional crystal structure of graphene as carbon was reported by Andre Geim and Konstantin Novoselov in 2004, it immediately caused a sensation around the world. Composed of a dense layer of carbon atoms wrapped in a honeycomb crystal lattice, graphene is only 0.35 nm thick, making it the thinnest two-dimensional material in the world. This...
