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.

我们的ERA团队致力于新型纳米结构胶束状聚合物离子液体(NCPIL)的合成、结构性能研究和应用。我们计划通过将疏水液体聚异丁烯(PIB)和热敏性聚恶唑烷(POX)结合在一起，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、溶解性、相容性和聚合物兼容性的热切换。NCPIL的努力需要对高度支化的多段聚电解质进行具有挑战性的定制。化学惰性的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。利用异丁烯和部分1，3-恶唑啉的活性阳离子嵌段共聚的最新进展，可以更好地了解控制纳米结构形成、相行为、聚合物相容性和热响应的参数。与传统胶束不同，NCPIL具有剪切和温度稳定性，因此在反应工程中提供了诱人的应用机会，甚至在聚合物熔体加工中作为添加剂。此外，NCPIL还将被定制用于智能材料，如自愈合弹性体/NCPIL纳米复合材料和独特的分子航天器，使催化活性纳米颗粒的可逆相转移成为可能。
