Rheological scaling of ionic-liquid-based polyelectrolytes in ionic liquid solutions: the effect of the ion diameter of ionic liquids

“…Polymerized ionic liquids (PILs) are a special type of polyelectrolytes with ionic liquid (IL) structures on their repeating units. 1 Since PILs combine unique features of ILs (e.g., CO 2 adsorption, high ionic conductivity, antimicrobial) with those of polymers (e.g., low glass transition temperatures, processability), they have attracted significant attention with applications in batteries, [2][3][4] molecular separations, 5,6 drug delivery, 7,8 lubrication, 9,10 and antimicrobial agents. [11][12][13] The performance of PIL-based materials can be further improved by adding solvents, e.g., ILs, as plasticizers.…”

Molecular bases for temperature sensitivity in supramolecular assemblies and their applications as thermoresponsive soft materials

“…Consequently, the soluble forms of the polymer are more favorable. 90,91 The UCST comparison between of polysulfopropylbetaine methacrylate (PSPB) and polysulfobutylbetaine methacrylate (PSBB) suggests that increasing the methylene chain length between the ammonium and the sulfonate moieties substantially increased the UCST temperature. 64 On the other hand, it has also been shown that lengthening methylene chain length between the backbone and the ammonium groups in poly(sulfobetaines) caused drastic decrease in UCST.…”

Antibiofouling Polyvinylidene Fluoride Membrane Functionalized by Poly(ionic liquid) Brushes via Atom Transfer Radical Polymerization

“…Poly­(ionic liquids) (PILs) are a new subclass of polyelectrolytes with unique physical and chemical properties and have recently attracted much attention as antibacterial materials. − PILs are formed by a relatively simple polymerization procedure of ionic liquid (IL) containing organic cations and inorganic anions , and demonstrate not only the advantages of high biocompatibility, broad-spectrum antibacterial properties, versatile molecular design, and high chemical stability of IL monomers but also the facile processability of polymer materials . Compared with conventional antibiotics which destroy specific biological processes to mitigate bacterial activity, PILs were reported to destroy cell membrane integrity and disturb potential balance through disrupting the lipid bilayer and electrostatic interaction, leading to leaking and eventual cell death. , These antibacterial mechanisms work rapidly and without entering the bacterial cells, making it hard to develop resistance.…”
