  摘要：

  通过RAFT聚合，使用末端炔基黄原酸酯作为转移剂，制备了不同聚合度（10、50和100）的聚离子液体（P(IL)s），单体转化率高达约80%，P(IL)100的ĐM为1.5。随后，将P(IL)链与15N标记的叠氮功能化羟乙基纤维素（HEC）偶联，形成具有不同链长和接枝密度的HEC接枝共聚物，通过（13C和15N）CP-MAS NMR和FT-IR光谱进行表征。HEC-g-P(IL)s对大肠杆菌和金黄色葡萄球菌的抗菌活性测试表明，其抗菌活性与已知的抗生素氨苄西林相当，显示了接枝共聚物对细菌的高效活性。此外，HEC-g-P(IL)s对大肠杆菌的抗菌效果略优于金黄色葡萄球菌。随着P(IL)10在HEC骨架上的接枝密度降低，接枝共聚物对两种细菌的活性均有所下降。这些发现表明，HEC-g-P(IL)有可能作为消毒剂化合物得到应用，例如在涂料配方中。

  methyl methacrylate (MMA) with activators generated by electron transfer (AGET ATRP) was done using microemulsion polymerization at the relatively low temperature of 30 °C. Ethyl 2-bromoisobutyrate (EBiB) was used as ATRP initiator, ascorbic acid (AA) was used as reducing agent, and CuCl2/N-bis(2-pyridylmethyl)octylamine (BPMOA) was used as catalyst. Microemulsion AGET ATRP of MMA was well-controlled

  使用微乳液聚合在30°C的相对较低的温度下进行了可持续的甲基丙烯酸甲酯（MMA）原子转移自由基聚合反应，该活化剂由电子转移生成的活化剂（AGET ATRP）进行。将2-溴异丁酸乙酯（EBiB）用作ATRP引发剂，将抗坏血酸（AA）用作还原剂，并将CuCl 2 / N-双（2-吡啶基甲基）辛胺（BPMOA）用作催化剂。MMA的微乳液AGET ATRP得到了很好的控制，生产了直径约5 nm且分子量分布窄的聚甲基丙烯酸甲酯（PMMA）纳米颗粒（M w / M n= 1.20-1.40）。在PMMA聚合和分离后，含有催化剂和ILs的混合物被证明是可回收和可循环使用的。补充引发剂，还原剂和单体（MMA）后，即使在第五个循环中，MMA的AGET ATRP仍可生产出分子量可再现且分子量分布窄的PMMA。因此，该过程被证明是可持续的。此外，使用新的表面活性剂IL配体，3- 11-[（3-（双（吡啶-2-基甲基）氨基）丙酰基）氧基]十一烷基}

  The disclosure generally relates to a dispersion of nanoparticles in a liquid medium. The liquid medium is suitably water-based and further includes an ionic liquid-based stabilizer in the liquid medium to stabilize the dispersion of nanoparticles therein. The stabilizer can be polymeric or monomeric and generally includes a moiety with at least one quaternary ammonium cation from a corresponding ionic liquid. The dispersion suitably can be formed by shearing or otherwise mixing a mixture/combination of its components. The dispersions can be used to form nanoparticle composite films upon drying or otherwise removing the liquid medium carrier, with the stabilizer providing a nanoparticle binder in the composite film. The films can be formed on essentially any desired substrate and can impart improved electrical conductivity and/or thermal conductivity properties to the substrate.

• Stimuli Responsive Poly(1-[11-acryloylundecyl]-3-methyl-imidazolium bromide): Dewetting and Nanoparticle Condensation Phenomena

  A stimuli-responsive homopolymer poly(ILBr) is fabricated via a "two-phase" atom transfer radical polymerization (ATRP) process, where ILBr stands for the reactive ionic liquid surfactant, 1-[11-acryloylundecyl]-3-methyl-imidazolium bromide. An extraordinarily wide molecular weight distribution (PDI = 6.0) was obtained by introducing the initiator (4-bromomethyl methyl benzoate) in a heterogeneous two-phase process. The molecular weight distribution of poly(ILBr) was characterized by size-exclusion chromatography (SEC). The resulting homopolymer was found to be surface active and stimuli responsive. Poly(ILBr) films coated on quartz exhibit stimuli-responsive dewetting after ion exchange of Br- by PF6-. This dewetting phenomenon can be understood in chain segmental terms as a stimuli-induced structural relaxation and appears to be the first such reported stimuli-responsive polymeric dewetting. Titrating aqueous poly(ILBr) with aqueous bis(2-ethylhexyl)sulfosuccinate induces nanophase separation and results in the condensation of nanoparticles 30-60 nm in diameter.
