The initiator is one type of initiator capable of releasing free radicals under the condition of heating, and preferably the initiator is one or two of di-tert-butyl peroxide, tert-butyl peroxybenzoate and azobisisobutyronitrile.

Performance testing
The polyionic liquid-based graphene color paste obtained in examples 1-5 of the present invention was compared with the graphene color paste of comparative examples 1-8. The particle size distribution of graphene in the color paste was tested by using a dispersity tester, and the test results are shown in table 1.
Table 1 particle size distribution test results of graphene in color paste
As can be seen from the data in Table 1, in the color paste prepared in examples 1 to 5, the particle size distribution of graphene is uniform, the particle size is between 105 and 242nm, and the stability of the color paste is good.
In contrast 1, as 4-vinyl imidazole is not added and no imidazole ring imidazole conjugated ring can form an anchoring effect on the surface of the graphene sheet layer through pi-pi conjugation effect, the graphene is not well dispersed, aggregation is very easy to occur during storage, the particle size of the graphene is obviously increased, the stability is reduced, and layering occurs after 48 hours of storage.
In comparative example 2, the 4-vinylimidazole can form a certain anchoring effect on the graphene, but has no synergistic effect of the 2-vinylpyrrole, the anchoring effect is weaker, agglomeration still occurs during storage, the particle size of the graphene is obviously increased, the stability is worse, and layering occurs after 72 hours of storage.
In comparative example 3, since allyl trimethyl ammonium chloride was not added, no charge layer was formed around the nanosheet layer, stability of the color paste was poor, particle size of graphene was continuously increased with time, and delamination occurred after 72 hours of storage.
In comparative example 4, since octadecyl methacrylate was not added, there was no steric hindrance between graphene sheets, aggregation was easy, the particle size of graphene was continuously increased with the increase of time, and delamination occurred after 48 hours of storage.
In comparative example 5, the addition of an excess of octadecyl methacrylate resulted in greater steric hindrance between graphene sheets, but the formation of entanglement between the excess paraffins resulted in increased agglomeration of the graphene particles, increased graphene particle size over time, and delamination after 48 hours of storage.
Comparative example 6 is a commercial graphene paste, and as can be seen from the data in table 1, the particle size of graphene increases with time, and delamination occurs after 720 hours of storage. Therefore, the graphene color paste prepared by the method has excellent particle size and stability.
