“…It is widely known, that imidazolium cation can support the stabilization of CNT dispersions via the cation-p interaction. [85,86] According to our results, thiazoliumcations in ionic polymer offer similar solubilizing effect. Moreover, MWCNTs stabilized with the thiazolium polymer can be easily transferred to organic solvents, such as acetone.…”

“…Mecerreyes et al [156] directly used poly(VeimBr) to stably disperse SWCNTs in solvents. In the work reported by Dubios et al [157], an imidazolium end-functionalized poly(L-lactide) (Imi-PLLA) was synthesized by ring-opening polymerization of L-lactide in the presence of a hydroxylated IL as an initiator, and then was used to assist dispersion of MWCNTs into chloroform.…”

Carbon nanotubes (CNTs) and graphene sheets are the most promising fillers for polymer nanocomposites due to their superior mechanical, electrical, thermal optical and gas barrier properties, as well as high flame-retardant efficiency. The critical challenge, however, is how to uniformly disperse them into the polymer matrix to achieve a strong interface for good load transfer between the two. This problem is not new but more acute in CNTs and graphene, both because they are intrinsically insoluble and tend to aggregate into bundles and because their surfaces are atomically smooth. Over the past decade, imidazolium ionic liquids (Imi-ILs) have played a multifunctional role (e.g., as solvents, dispersants, stabilizers, compatibilizers, modifiers and additives) in the fabrication of polymer composites containing CNTs or graphene. In this review, we first summarize the liquid-phase exfoliation, stabilization, dispersion of CNTs and graphene in Imi-ILs, as well as the chemical and/or thermal reduction of graphene oxide to graphene with the aid of Imi-ILs. We then present a full survey of the literature on the Imi-ILs assisted fabrication of CNTs and graphene-based nanocomposites with a variety of polymers, including fluoropolymers, hydrocarbon polymers, polyacrylates, cellulose and polymeric ionic liquids. Finally, we give a future outlook in hopes of facilitating progress in this emerging area. OPEN ACCESSPolymers 2013, 5 848

“…Recently, the researchers have focused on poly(ionic liquid)s (PILs) from the polymerization of IL monomers [16]. Compared to their monomers, the PILs possess good processability and membrane forming ability with potential in polymeric electrolytes, carbon dioxide absorbing materials, catalytic membranes, ionic conductive materials and microwave absorbing materials [17][18][19][20][21][22][23][24]. Different from normal water soluble polyelectrolytes, PILs can be tunable as hydrophobic but soluble in strong polar organic solvent such as DMF and DMSO by introducing the hydrophobic counter-ions (e.g., PF 6 − , Tf 2 N − ) [25].…”

Abstract:The hydrophobic poly(ionic liquid) of poly(3-ethyl-1-vinylimidazolium bis(trifluoromethanesulfonyl)imide) (PVI-TFSI) containing imidazolium cations and bis(trifluoromethanesulfonyl)imide anions was synthesized for the separation of methyl blue and chromium ions [Cr(VI)] from water. The adsorption of methyl blue and Cr(VI) in PVI-TSFI/water system reached equilibrium stage within 60 min and 12 h, and the maximum adsorbed percentage for methyl blue and Cr(VI) was 97.6% and 98.0%, respectively. The adsorption regi me of either methyl blue or Cr(VI) for PVI-TFSI was in correspondence with the Langmuir adsorption model. The maximum adsorption capacity of PVI-TFSI for methyl blue and Cr(VI) was determined as 476.2 and 17.9 mg/g, respectively. The hydrophobic poly(ionic liquid) with a remarkable adsorbent capacity of methyl blue and Cr(VI) can be conveniently synthesized and shows potential in water treatment for the effective separation of organic dyes or heavy metal ions.
