Hierarchically Nanostructured Polyisobutylene-Based Ionic Liquids

Abstract: A new type of highly temperature stable ionic liquid (IL) with strongly temperature dependent nanostructures is reported. The molecular design relies on the use of a liquid polymer with an ionic liquid headgroup, introducing liquid properties by both the polymeric and the ionic liquid (IL) headgroup. The IL polymers (poly(isobutylene)s) 3a–3c (PIB-ILs) were prepared by a combination of living carbocationic polymerization (LCCP) and subsequent “click” chemistry for attachment of methylimidazolium (3a), pyrrolid… Show more

“…The temperature increase weakens the electrostatic interaction between the ionic clusters leading to an increase in mobility of polymer chains. 22 There are, however, remarkable differences between different materials: The methylimidazolium-based cation (PIB-IL 3a) is stable (up to nearly 300°C), but structural recovery is slowed down or does even not take place due to thermal decomposition (see Figure 5 and Ref. 22 ).…”

“…Thus, a large structural variety of hydrogen bonding moieties exists, which allows tuning of the stability/lability and, therefore, of the inherent dynamics of hydrogen-bonded polymers. However, self-healing is not only determined by the absolute strength of the applied hydrogen bonds [25], but also by phase segregation effects between the polymeric interphases [26,27]. The strength of hydrogen bonds in the solid and melt states of polymers is generally not known and is certainly different from the values known from polymer solutions.…”
