Problems solved by technology

One is that ultra-high temperature reaction is required, the equipment is expensive, and energy consumption is high; the other is that the reaction often requires the use of rare metal ruthenium as a substrate or extremely dangerous and flammable alkali metals such as sodium and potassium as raw materials, harsh operating conditions, and high production costs.
It can be seen that the existing preparation methods of unsaturated carbon-based materials such as graphene have certain deficiencies, and cannot meet the needs of green and efficient large-scale preparation

Embodiment 1

[0015] When replacing R in the methane (I) type initiator 1 is a hydrogen atom, R 2 , R 3 and R 4 are chlorine atoms. An equivalent amount of starting material and diethylamine were heated and refluxed under normal pressure for 24 hours. After the reaction was completed, the by-products were removed by rotary evaporation, and extracted and purified to obtain an unsaturated carbon-based material (a class of graphite) that could be redispersed in the solution. ene nanosheets).

Embodiment 2

[0017] Excess diethylamine was used in the reaction as described in Example one.

Embodiment 3

[0019] As described in Example 1, the reaction to prepare the unsaturated carbon-based material was carried out at a pressure above one atmosphere.
