Room-temperature molten salt polymers as a matrix for fast ion conduction

Vinyl polymers having either imidazolium group or sulfonamide group in the side chain were prepared as components to form a molten salt. After mixing, these polymers formed a molten-salt-like flexible domain in the polymer, and excellent ionic conductivity (7.52 X 10-6 Scm-1 and 1.88 X 10-4 Scm-1 at 30°C, respectively) was observed in spite of their rubber-or powder-like properties.

Efficient heterogeneous functionalized polymer ionic liquid catalyst for the synthesis of ethylene carbonate via the coupling of carbon dioxide with ethylene oxide

A series of functionalized polymer ionic liquids (PILs) were synthesized and immobilized onto a 4 A molecular sieve. The catalytic activity of the resulting heterogeneous catalyst toward the synthesis of ethylene carbonate (EC) via the cycloaddition reaction of ethylene oxide (EO) and CO2 was studied. The effects of the reaction conditions such as reaction temperature, pressure, time, and the amount of catalyst used, were systematically investigated. A high yield of EC and excellent selectivity could be obtained under optimized conditions. The catalyst is thermally stable and shows good reusability. Based on the experimental results, a plausible reaction mechanism has been proposed for the catalytic reaction. This journal is the Partner Organisations 2014.

Rhodium nanoparticles stabilized by ionic copolymers in ionic liquids: Long lifetime nanocluster catalysts for benzene hydrogenation

Novel ionic liquid-soluble ionic copolymers containing imidazolium ionic liquidlike units have been synthesized. Rhodium nanoparticles stabilized by the ionic copolymer in ionic liquids have been successfully obtained. The nanoparticles showed unprecedented lifetime and activity in arene hydrogenation under forcing conditions (a temperature of 75 °C and a hydrogen pressure of 40 bar) with a total turnover (TTO) of 20000 (in five total recycles of 4000 TTOs each) and a turnover frequency of 250 h-1, demonstrating that the combination of ionic liquids with ionic liquidlike stabilizers is a pathway towards highly stable and active nanoparticle catalysts.

Poly(ionic liquid) and macrocyclic polyoxometalate ionic self-assemblies: New water-insoluble and visible light photosensitive catalysts

Several poly(ionic liquid)s (PILs) were synthesized and assembled with a multielectronic-process sustaining polyoxometalate (POM) into new green and water-insoluble nanomaterials (POM@PILs). They are visible light photosensitive, unlike their two componen

Influence of tethered ions on electric polarization and electrorheological property of polymerized ionic liquids

Polymerized ionic liquids (PILs) show potential to be used as new water-free polyelectrolyte-based electrorheological (ER) material. To direct ER material design at the molecular level, unveiling structure-property relationships is essential. While a few studies compare the mobile ions in PILs there is still a limited understanding of how the structure of tethered counterions on backbone influences ER property. In this study, three PILs with same mobile anions but different tethered countercations (e.g., poly(dimethyldiallylammonium) P[DADMA]+, poly(benzylethyl) trimethylammonium P[VBTMA]+, and poly(1-ethyl-4-vinylimidazolium hexafluorophosphate) P[C2VIm]+) are prepared and the influence of tethered countercations on the ER property of PILs is investigated. It shows that among these PILs, P[DADMA]+ PILs have the strongest ER property and P[C2VIm]+ PILs have the weakest one. By combining dielectric spectra analysis with DFT calculation and activation energy measurement, it can clarify that the influence of tethered counterions on ER property is mainly associated with ion-pair interaction energy that is affecting ionic conductivity and interfacial polarization induced by ion motion. P[DADMA]+ has the smallest ion-pair interaction energy with mobile ions, which can result in the highest ionic conductivity and the fastest interfacial polarization rate for its strongest ER property.

Synthesis of polymeric nanoparticles containing reduced graphene oxide nanosheets stabilized by poly(ionic liquid) using miniemulsion polymerization

Polymeric nanoparticles containing reduced graphene oxide (rGO) nanosheets have been prepared by aqueous miniemulsion radical polymerization of methyl methacrylate (MMA) utilizing poly(ionic liquid) (PIL) as stabilizer to effectively disperse the rGO nanosheets in the monomer phase. The PIL that gave the best results in terms of rGO dispersibility was a block copolymer of the ionic liquid monomer 1-(2-methacryloyloxyethyl)-3-butylimidazolium bis(trifluoromethanesulfonyl)amide ([Mbim][TFSA]) and MMA, the concept being that the MMA units impart solubility in the MMA monomer droplets whereas the IL units act as adsorption sites for rGO. The rGO dispersibility in vinyl monomer was demonstrated to be superior using the above PIL block copolymer compared to the corresponding statistical copolymer or PIL homopolymer. Overall, the approach developed demonstrates how PILs can be employed to conveniently switch (turn ON/OFF) the dispersibility of PIL/rGO via anion exchange reactions, which can be an efficient strategy for synthesis of polymer/rGO nanocomposite materials.

Efficient fixation of CO2 into cyclic carbonates catalyzed by hydroxyl-functionalized poly(ionic liquids)

A series of hydroxyl-functionalized poly(ionic liquids) (PILs) were synthesized and employed as catalysts for the synthesis of cyclic carbonates from CO2 and epoxides without the use of any co-catalyst or organic solvent. It was demonstrated th

Ionic liquid polymer materials with tunable nanopores controlled by surfactant aggregates: A novel approach for CO2capture

Monomeric ionic liquids (ILs), ionic liquid polymers (ILPs) and IL-based composites have emerged as potential materials for CO2 capture owing to their exceptional intrinsic physical solubility of CO2. This study reports the development of novel IL polymer materials incorporating CO2-philic tunable nanopores and their subsequent utilization for CO2 capture. In this approach, primarily, micelles were formed in monomeric IL 1-vinyl-3-ethylimidazolium bis(trifluoromethylsulfonyl)imide using a CO2-philic surfactant (N-ethyl perfluorooctyl sulfonamide) through self-assembly, from which polymeric materials were fabricated via free radical polymerization. The CO2 adsorption studies demonstrated 3-fold enhancements for the surfactant micelle incorporated IL polymers (SMI-ILPs) compared to their bare IL polymers. The SMI-ILPs were regenerated by simply heating at 70 °C and reused for 15 cycles with a retention of over 96% of CO2 uptake capacity. The simple recovery and notable enhancements in CO2 sorption of novel SMI-ILPs were traced to the adsorption of CO2 at the (i) highly porous IL-based polymeric networks, and (ii) nanometer sized apolar pores made by CO2-philic surfactant tails. This work will open up new possibilities for the development of IL based smart materials for CO2 capture and separation. This journal is
