摘要：我们合成了一种新型聚离子液体（PIL），并开发了一种允许氧化石墨烯（GO）从水到有机溶剂相转移的方法，在各种有机溶剂，特别是非极性有机溶剂中保留氧化石墨烯液晶（GOLC）相。 PIL ([PEP-MIM]DBS) 在此过程中被用作非共价功能材料，能够将 GO 从水相转移到非极性有机相。 PILs 可以非共价修饰 GO，并使 GO 纳米片在固态 PILs/GO 杂化物中保持剥离，该杂化物可以很好地再分散在有机溶剂中而不会发生任何团聚。这将能够支持 GOLC 相的已知溶剂的数量扩大到二甲基甲酰胺、二甲亚砜、乙腈、四氢呋喃和许多其他非极性有机溶剂，其中许多在本报告之前并不知道能够提供 GOLC 相，例如二氯甲烷、四氯甲烷、二氯乙烷和四氯乙烷。图解摘要
ABSTRACT We synthesise a novel poly(ionic liquid) (PIL) and develop a procedure that allows the phase transfer of graphene oxides (GO) from water to organic solvent, retaining graphene oxide liquid crystal (GOLC) phase in various organic solvents, especially non-polar organic solvents. PIL ([PEP-MIM]DBS) is exploited in this procedure as a noncovalent functional material that is capable of transporting GO from aqueous to non-polar organic phase. PILs can decorate GO noncovalently and keep GO nano-sheets exfoliated in solid-state PILs/GO hybrids, which can well redisperse in organic solvents without any agglomeration. This expands the number of known solvents which can support GOLC phase to dimethyl formamide, dimethyl sulfoxide, acetonitrile, tetrahydrofuran, and a number of other non-polar organic solvents, many of which were not known to afford GOLC phase prior to this report, such as dichloromethane, tetrachloromethane, dichloroethane and tetrachloroethane.
