Graphene intercalation compound as well as preparation method and application thereof
The invention provides a graphene intercalation compound as well as a preparation method and application thereof. The graphene intercalation compound provided by the invention comprises graphene oxide and a polymer grafted on the graphene oxide, and the polymer comprises a structural unit derived from 2-acrylamide-2-methylpropanesulfonic acid and a structural unit derived from a second monomer, the second monomer is selected from at least one of unsaturated acids and salts thereof. Graphene oxide with a large number of oxygen-containing functional groups on the surface is copolymerized with a specific monomer, and a polymer is grafted on a graphene sheet layer, so that a graphene intercalation compound with a specific structure is obtained, and the purpose of improving the dispersing performance of a graphene material in cement paste is achieved; meanwhile, the intercalation compound can replace a traditional oil well cement dispersing agent, and the effect of improving the fluidity of slurry in a cement slurry system is achieved.
本发明提供一种石墨烯插层复合物及其制备方法和应用。本发明所提供的石墨烯插层复合物包括：氧化石墨烯以及接枝在所述氧化石墨烯上的聚合物，所述聚合物包括衍生自2‑丙烯酰胺‑2‑甲基丙磺酸的结构单元和衍生自第二单体的结构单元，其中，所述第二单体选自不饱和酸和其盐中的至少一种。通过使表面含有大量的含氧官能团的氧化石墨烯与特定的单体共聚，在石墨烯片层上接枝上聚合物，得到一种具有特定结构的石墨烯插层复合物，达到改善石墨烯材料在水泥浆中分散性能的目的，同时该插层复合物能够代替传统的油井水泥分散剂，在水泥浆体系中起到改善浆体的流动性的作用。
