Interaction between amphiphilic ionic liquid 1-butyl-3-methylimidazolium octyl sulfate and anionic polymer of sodium polystyrene sulfonate in aqueous medium

Aggregation Behavior of Polyether Based Siloxane Surfactants in Aqueous Solutions: Effect of Alkyl Groups and Steric Hindrance

“…Comparison with Si 3 -PG shows that the value of I 1 / I 3 for Si 4 -PG was smaller due to the three trimethylsiloxyls on the hydrophobic groups. Meanwhile, owing to the introduction of the ethyl group, Et-Si 3 -PG cannot be closer with each other and resulted in a less tight packing of the palisade layer, leading to more water molecules existing in the palisade layer of the Et-Si 3 -PG micelles, consequently causing pyrene molecules to sense a more polar microenvironment and then having higher I 1 / I 3 values; meanwhile, with a higher alkyl group (propyl, butyl) and branched chain in the siloxane group, polyether based siloxane surfactants could have more hydrophobic solubilizing sites for the pyrene probe and hence a decrease in I 1 / I 3 values. ,− …”

New ternary water-soluble support from self-assembly of β-cyclodextrin-ionic liquid and an anionic polymer for a dialysis device

“…The formation of the complex between anionic PSS and amphiphilic IL has been already studied and has found applications as magnetic nanoparticles for conductive membrane (Jiao and al. 2015;Barhoumi et al 2016). When long-chain imidazolium is used as a surfactant, electrostatic and hydrophobic interactions drive self-assembly between the PSS backbones and the alkyl tail to form ordered micelles with speci c surface tension useful in colloid and interface sciences.…”

Self-assembly of a short-chain ionic liquid within deep eutectic solvents

“…23 It is important to have a clear picture on the micellization and interfacial behaviour of short-chain IL based surfactants to concern them effectively in particular elds. [23][24][25] Several methods, such as, electrical conductivity, surface tension, dynamic light scattering (DLS), uorescence, UV-visible and NMR spectroscopic techniques has been successfully utilized to study their micellization and interfacial behavior. [24][25][26][27] Due to their structural exibility and outstanding properties, shortchain IL based surfactant systems have generated immense signicance, which is revealed in the increasing number of applications that have been reported in recent years.…”
