Designing melt flow of poly(isobutylene)-based ionic liquids

Timescales of self-healing in human bone tissue and polymeric ionic liquids

“…The influence of the anion can be investigated after an anion exchange: In our case, bromide was exchanged with bis(trifluoromethylsulfonyl)imide lithium salt (anion Tf 2 N). 23 This synthesis step leads, together with the respective ionic end group, to the materials PIB-IL 6a-6c. Figure 1 shows a scheme of the structure of these POILs, differing in their ionic interaction as well by the cation and the anion.…”

Vapor Phase Alkyne Coating of Pharmaceutical Excipients: Discrimination Enhancement of Raman Chemical Imaging for Tablets

“…A nucleophilic attack of triethylamine on the propargyl halide in the vapor phase resulted in the formation of a quaternary ammonium salt, and this compound adhered on the surface of silica gel (Scheme ). Although this ammonium salt has been reported as a substrate for click chemistry to create various functional polymers, our study was the first to form this ammonium salt in a vapor phase reaction and use it for Raman chemical imaging.…”

Hierarchically Mesostructured Polyisobutylene‐Based Ionic Liquids

“…The characterization of the prepared polyisobutylene‐ionic liquids ( 1 H‐ and 13 C‐NMR‐analyses, ATR‐IR‐analyses, GPC‐measurements, MALDI‐TOF‐MS‐analyses as well as TGA and DSC measurements) were conducted according to the literature . Small‐angle X‐ray scattering experiments were conducted using the same instrumentation and evaluation methods as described in the previous work …”

“…Despite the structural similarity of PILs to classical ionomers, PILs should show an even more complex microphase separation due to the combination of the well‐known nanoscale ordering of classical monomeric ionic liquids (intermediate range order, ≈5–10 Å) combined with the mesoscale ordering of ionomeric polymeric materials (5–20 nm) . The mesoscale ordering and self‐aggregation of PILs can be tuned by the specific design of ionic liquid polymers and copolymers, leading to favorable properties in different fields of application e.g., as electrolytes in electrochemical devices, as self‐assembling liquid‐crystalline materials, in nanoelectronics (such as in ionic liquid gating,) in nanolithography or as self‐healing materials . The lowering of glass transition temperatures ( T g ) of PILs combined with their specific designs can display numerous advantages like significant increase of conductivity …”
