Abstract

The invention relates to a method for preparing graphene by utilizing D-glucosamine derivatives. According to the method, components including, in percentage by mass, 0.01%-10% of a 2-(3-carboxyl-1-acylamino)-2-desoxy-D-glucosamine aqueous solution, 0.0001%-10% of a reducing agent aqueous solution and an oxidized graphene solution with the concentration being 0.01g / L-1 g / L are mixed in the volume ratio being (10:1:2)-(1:1:2) and stirred for 30-600 minutes at the temperature of 20 DEG C-60 DEG C, a graphene solution is obtained and repeatedly washed with ethyl alcohol and deionized water, centrifugation is performed, and graphene powder is obtained after drying treatment. The method is green, environment-friendly, low in cost and simple in process, and the graphene solution is prepared and has good dispersibility and stability.

Description

technical field [0001] The invention belongs to the technical field of graphene synthesis and nanomaterials, in particular to a method for preparing graphene from D-glucosamine derivatives. Background technique [0002] In 2004, Andre Heim and Konstantin Novoselov, physicists at the University of Manchester in the UK, successfully separated graphene with single-layer atomic arrangement from graphite by tearing scotch tape. Therefore, he won the Nobel Prize in Physics in 2010 (Science, 2004, 306(5696):666-669). Graphene consists of carbon atoms with sp 2 The hybrid orbitals form a hexagonal honeycomb lattice, and its structural unit is a carbon six-membered ring, which is a two-dimensional material with a thickness of only a single layer of carbon atoms. Graphene is the basic structural unit that constitutes carbon-based materials. It can be wrapped to form zero-dimensional Fullerenes, rolled into one-dimensional carbon nanotube, and stacked layer by layer to form three-di...
