  Polymeric ionic liquids based on ether functionalized ammoniums and perfluorinated sulfonimides

  摘要：

  A new family of polymeric ionic liquids (PILs) based on alkyl and alkyl ether substituted ammoniums and perfluorinated sulfonimides (i.e., bis(fluorosulfonyl)imide (FSI-), and bis(trifluoromethanesulfonyl)imide (TFSI-)) have been synthesized by polymerization of the corresponding ionic liquid monomers (ILMs). Their structures and compositions have been characterized by H-1 and F-19 NMR, FTIR and viscosity-average molecular weight (M-v). The physicochemical properties of both the ILMs and the PILs have been studied in terms of thermal stability, phase transition, and ionic conductivity. All the prepared ILMs and PILs reveal excellent thermal stabilities to greater than 250 degrees C. The PILs containing alkyl ether side unit show significant decrease in glass transition temperature (T-g), the values of T-g of the alkyl ether based-PILs are all significantly lower by 10-77 degrees C in magnitude than those of the corresponding alkyl based ones. The ionic conductivity of alkyl ether based-PILs in the best case increases up to 4.0 x 10(-6) S cm(-1) at 30 degrees C, and reaches 7.6 x 10(-5) S cm(-1) at 60 degrees C, and outperform their ammonium counterparts with alkyl side chain that were synthesized as references.

  用于将 CO2 和环氧化物吸收转化为环状碳酸酯的聚合物离子液体膜

  摘要：

  聚合物离子液体膜 (PILM) 通过光引发聚合 DMAEMA 基离子液体 (IL) 和共聚单体将 CO 2转化为环状碳酸酯而制备。研究了官能团和阴离子的影响，以找到最佳的离子液体单体。基于 [DMAEMA-EtOH]Br 的 PILM 表现出最高的碳酸丙酯 (PC) 产率 (98%)，接近 [DMAEMA-EtOH]Br 单体的产率。此外，PILMs可以催化气态环氧丙烷（PO）和CO 2转化为 PC 的 PO 转化率为 87.3%，而纯聚合离子液体的 PO 转化率仅为气态 PO 的 3.1%。优异的催化活性可归因于 PILM 的高活性催化位点和出色的溶胀能力。干燥的 PILM 可以吸收 PO 蒸气并溶胀成具有丰富孔隙的膜，其中含有丰富的活性位点，可有效地将 PO 和 CO 2催化为 PC。

In addition, cytotoxicity of these mixed micelles can be markedly reduced by PPEG compared with their corresponding PQAs, but their good antibacterial activities are still maintained to a certain degree, as evaluated

  为了研究聚（季铵）盐（PQAs）与聚（乙二醇）在自然条件下的相互作用对混合胶束表面结构和性能的影响，首先设计了一系列PQA，并通过原子转移法合成了使用分别由溴丁烷，溴辛烷和溴十二烷季铵化的甲基丙烯酸2-（二甲氨基）乙酯（DMAEMA）进行自由基聚合（ATRP）。还通过ATRP使用聚（乙二醇）甲基醚甲基丙烯酸酯制备了具有相似聚合度的聚（聚乙二醇）甲基醚甲基丙烯酸酯（PPEG）。接下来，将这些PQA与等重量的PPEG在水中混合，以交叉组装成混合胶束。这些混合胶束的结构和特征通过荧光测量来表征，1个H NMR）和氢-氢相关光谱核磁共振（H-H COZY NMR）。这些结果表明，PQA和PPEG混合物可以交叉组装成具有低CMC的混合胶束。可以通过改变季铵盐中的烷基链长度来定制PQA和PPEG混合物的表面结构，粒度，尺寸分布和Zeta电位，并且烷基链长度也会影响季铵盐的分布和烷基链取向在混合的胶束表

  In this paper, macroporous antimicrobial polymeric gels (MAPGs) functionalized with active quaternary ammonium cations attached to varying hydrocarbon chain lengths have been fabricated. Apart from the change in the alkyl chain length attached to the quaternary ammonium cation, the amount of crosslinker was also varied during the fabrication of the macroporous gels.

• Influence of Zwitterions on Thermomechanical Properties and Morphology of Acrylic Copolymers: Implications for Electroactive Applications

  n-Butyl acrylate-based zwitterionomers and ionomers containing 3-[[2-(methacryloyloxy)ethyn(dimethypammonio]-1-propanesulfonate (SBMA) and 2-[butyl(dimethyl)amino]ethyl methacrylate methanesulfonate (BDMAEMA MS), respectively, were synthesized using conventional free radical polymerization. Size-exclusion chromatography confirmed the molecular weights of the copolymers exceeded the critical molecular weight between entanglements (Me) for poly(n-butyl acrylate). Differential scanning calorimetry (DSC), small-angle X-ray scattering (SAXS), and atomic force microscopy (AFM) revealed that zwitterionomers promoted more well-defined microphase separation than cationic analogues. Dynamic mechanical analyses (DMA) of the copolymers showed a rubbery plateau region due to physical cross-links between charges for zwitterionomers only. Since SBMA and BDMAEMA MS have very similar chemical structures, we attributed improved microphase separation and superior elastomeric performance of the zwitterionomers to stronger association between covalently tethered charged pairs.
