ERA-CHEMISTRY_Nano-Compartmentalized Polymeric Ionic Liquids as a New Material Platform for Tailoring Responsive Macromolecular Systems

我们ERA团队的工作目标是合成一种新型的具有胶束状拓扑结构的纳米结构聚合物离子液体（NCPIL），结构-性质研究和应用。我们计划通过将疏水性液体聚异丁烯（PIB）和热响应性聚恶唑啉（POX）结合在一起来创建独特的化学和物理稳定的纳米结构，从而实现纳米结构的形成以及极性，溶解度，可溶解性和聚合物相容性的热切换。NCPIL的努力需要具有挑战性的剪裁高度支化的分段聚电解质。化学惰性PIB对于实现NCPIL的化学稳定性、低玻璃化转变温度和低粘度是必不可少的。利用最近的进展，在生活中的阳离子嵌段共聚异丁烯和选定的1，3-恶唑啉，使更好地了解参数的纳米结构的形成，相行为，聚合物的相容性和热响应。与传统的胶束不同，NCPIL具有剪切和温度稳定性，因此为它们在反应工程中的应用甚至作为聚合物熔体加工中的添加剂提供了有吸引力的机会。此外，NCPIL还将被定制为智能材料，如自修复弹性体/NCPIL纳米复合材料和独特的分子梭，使催化活性纳米颗粒的可逆相转移成为可能。

Our ERA team effort aims at synthesis, structure-property investigations and applications of a new type of nanostructured polymer ionic liquids with micelle-like topologies (NCPIL). We plan to create unique chemically and physically stable nanostructures by joining together hydrophobic liquid polyisobutylenes (PIB) and thermoresponsive polyoxazolines (POX), thus enabling nanostructure formation as well as thermal switching of polarity, solubility, miscibility, and polymer compatibility. The NCPIL effort requires challenging tailoring of highly branched segmented polyelectrolytes. The chemically inert PIB is essential for achieving chemical stability, low glass transition temperature and low viscosity of NCPILs. Exploiting recent advances in living cationic block copolymerizations of isobutylene and selected 1,3-oxazolines enables the better understanding of parameters governing the nanostructure formation, phase behavior, polymer compatibility and thermoresponse. Unlike conventional micelles, NCPILs are shear and temperature stable, thus offering attractive opportunities for their applications in reaction engineering and even as additive in polymer melt processing. Moreover, NCPILs will also be tailored for applications as smart materials such as self-healing elastomer/NCPIL nanocomposites and unique molecular shuttles, enabling reversible phase transfer of catalytically active nanoparticles.
