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

  DOI：10.1039/c6sm00269b

  日期：——

  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

  通过使用聚（离子液体）（PIL）作为稳定剂使甲基丙烯酸甲酯（MMA）进行水微乳液​​自由基聚合，以有效地将rGO纳米片分散在单体相中，制备了包含还原性氧化石墨烯（rGO）纳米片的聚合物纳米粒子。在rGO分散性方面获得最佳结果的PIL是离子液体单体1-（2-甲基丙烯酰氧基乙基）-3-丁基咪唑鎓双（三氟甲磺酰基）酰胺（[Mbim] [TFSA]）和MMA的嵌段共聚物这是因为MMA单元赋予了MMA单体液滴溶解性，而IL单元则充当了rGO的吸附位。与相应的统计共聚物或PIL均聚物相比，使用上述PIL嵌段共聚物证明rGO在乙烯基单体中的分散性更好。全面的，通过阴离子交换反应，这可能是合成聚合物/ rGO纳米复合材料的有效策略。

  Novel fluorescent solid sensors for Fe3+ detection in aqueous medium have been developed by photopolymerization of N-vinylpyrrolidone (VP), butyl acrylate (BA) and imidazolium-based ionic liquids obtained by anion change (Br−, BF4−, TFSI− and PF6−). The correlation between the hydrophilicity and the stability of the membranes was established, as well as the influence of the anion in their behavior

  AbstractSolid imidazolium‐based poly(ionic liquid)s with variable molecular weights that contain the poly[2‐(1‐butylimidazolium‐3‐yl)ethyl methacrylate] (BIEMA) cation and different counter anions were evaluated in terms of CO2 capture and compared with classical ionic liquids with similar counter anions. In addition to poly(ionic liquid)s with often‐applied ions such as BF4−, PF6−, NTf2−, trifluoromethanesulfonate (OTf−) and Br−, for the first time [BIEMA][acetate] was synthesised, which revealed a remarkably high CO2 sorption performance that exceeded the poly(ionic liquid)s studied previously on average by a factor of four (12.46 mg gPIL−1). This study provides an understanding of the factors that affect CO2 sorption and a comparison of the CO2 capture efficiency with the frequently used sorbents. Moreover, all the studied sorbents were reusable if regenerated under carefully selected conditions and can be considered as suitable candidates for CO2 sorption.
• Anion exchanged polymerized ionic liquids: High free volume single ion conductors

  日期：2011.3

  In this study, we investigate the isolated effect of anion type on the chemical, thermal, and conductive properties of imidazolium-based polymerized ionic liquids (PILs). PILs with various anions at constant average chain length were prepared by ion exchange with a water-soluble PIL precursor, (poly(1-[(2-methacryloyloxy)ethyl]-3-butylimidazolium bromide) (poly(MEBlm-Br)). NMR, IR, and elemental analysis confirm that anion exchange of ploy(MEBlm-Br) with bis(trifluoromethanesulfonyl) imide (TFSI), tetrafluoroborate (BF4), trifluoromethanesulfonate (Tf), and hexafluorophosphate (PF6) in water resulted in nearly fully exchanged PILs. As a function of anion type, the glass transition temperature plays a dominant role, but not the sole role in determining ion conductivity. Other factors affecting ionic conductivity include the size and symmetry of the anion and dissociation energy of the ion pair. Both the Vogel-Fulcher-Tammann (VFT) and Williams-Landel-Ferry (WLF) equations were employed to investigate the temperature dependent ionic conductivities. The C-1(g) (9.03) and C-2(g) (168 K) values obtained from the WLF regression of these PILs greatly deviate from the classical WLF values originally obtained from the mechanical relaxation of uncharged polymers (C-1(g) = 17.44, C-2(g) = 51.6 K) and the WLF values obtained from the conductive properties of other polymer electrolytes. This suggests that the fractional free volume (f (T-g) = B/(2.303C(1)(g))) and Vogel temperature (T-0 = Tg - C-2(g)) are strong functions of ion concentration, where high free volume allows for ion mobility at temperatures farther below the glass transition temperature of the polymer.
