Multifunctional hydrogel based on ionic liquid with antibacterial performance

Biocompatible antibacterial hydrogels as novel dressing materials have been a widely researched method in modern medical technology. Here, we designed and prepared a new type of multifunctional antibacterial hydrogels that used poly(vinyl alcohol) (PVA)-tetrahydroxyborate anion (B(OH)4 ?) hydrogel as a vector and pyrrolidinium ionic liquids (ILs) as antibacterial drugs. The formation of borate ester bonds between PVA and B(OH)4 ? as dynamic network junctions endows hydrogels with multiple functions. Moreover, the as-prepared hydrogel exhibited effective anti-microbial activity against Escherichia coli and Staphylococcus aureus. Our results indicated that the hydrogels containing ILs with longer alkyl chain exhibited more pronounced antibacterial properties. The moisture retention, self-healing, syringeability and multiresponse behavior together with the antibacterial properties of the hydrogels make them ideal candidates as multifunctional dressing materials for joint skin wound healing.

Tuning ionic liquids for hydrate inhibition

Pyrrolidinium cation-based ionic liquids were synthesized, and their inhibition effects on methane hydrate formation were investigated. It was found that the ionic liquids shifted the hydrate equilibrium line to a lower temperature at a specific pressure,

Chemical Vapor Deposition of Ionic Liquids for the Fabrication of Ionogel Films and Patterns

Film deposition and high-resolution patterning of ionic liquids (ILs) remain a challenge, despite a broad range of applications that would benefit from this type of processing. Here, we demonstrate for the first time the chemical vapor deposition (CVD) of ILs. The IL-CVD method is based on the formation of a non-volatile IL through the reaction of two vaporized precursors. Ionogel micropatterns can be easily obtained via the combination of IL-CVD and standard photolithography, and the resulting microdrop arrays can be used as microreactors. The IL-CVD approach will facilitate leveraging the properties of ILs in a range of applications and microfabricated devices.

Controlling the reactions of 1-bromogalactose acetate in methanol using ionic liquids as co-solvents

The reactions of an acetobromogalactose in mixtures of methanol and one of seven different ionic liquids with varying constituent ions were studied. In general, small amounts of ionic liquid in the reaction mixture led to increases in the rate constant compared to methanol, whilst large amounts of ionic liquid led to decreases in the rate constant; this outcome differs significantly from previous reactions proceeding through this mechansim. Temperature dependent kinetic studies indicated that the dominant interaction driving these changes was between the ionic liquid and the transition state of the process. Through considering solvent parameters of ionic liquids, a relationship was found between the changes in the rate constant and both the hydrogen bond accepting ability and polarisability of the solvent, indicating that the interactions affecting reaction outcome are both specific and non-specific in nature; once more, these interactions were different to those observed in previous similar reactions. By changing the amount of ionic liquid in the reaction mixture, additional products not seen in the molecular solvent case were observed, the ratios of which are dependent on the anion of the ionic liquid and the proportion of ionic liquid in the reaction mixture. This demonstrates the importance of considering solvent effects on both the rate and product determining steps and the potential application of such changes is discussed.
