The dilational rheology and splashing behavior of ionic liquid-type imidazolium Gemini surfactant solutions: Impact of alkyl chain length

Rheological and Mechanical Properties of Silica/Nitrile Butadiene Rubber Vulcanizates with Eco-Friendly Ionic Liquid

“…ILs are of various types, such as pyridinium-, imidazolium-, pyrrolidinium- and ammonium and phosphonium-based, etc. [ 34 ]. Imidazolium-based ILs consist of a cationic imidazolium ring and have applications in the nuclear industry, while 1-butyl-3-methyl imidazolium chloride is used as an electrolyte to recover uranium from spent nuclear fuel [ 35 ].…”

“…For ILs used in polymer nanocomposites, it is essential to understand the variations of thermodynamics and the dynamics of polymer chains. Non-volatile, low toxicity and ecofriendly ILs exhibit great potential in rubber nanocomposite formulation [ 34 , 36 , 37 ] due to their ability to regulate the dispersions of fillers [ 38 , 39 ] and zinc oxide activators, the filler–rubber interfacial interactions [ 40 ] and the crosslinking density of the matrix, as well as the rheological, mechanical, optical, and thermal properties of the nanocomposites [ 41 , 42 ]. Phosphoniums demonstrate a catalyst role for the silanization reaction between silica and Si69 in styrene-butadiene rubber nanocomposites, which generally improves the silica dispersion and the silica–rubber interfacial interactions [ 21 ].…”

Recent developments in sustainable corrosion inhibitors: design, performance and industrial scale applications

“…Nevertheless, increase in hydrophobicity can adversely affect the solubility of such ionic liquids in the polar electrolytes. Therefore, a proper combination of hydrophilicity and hydrophobicity is highly essential while designing the effective corrosion inhibitors [389,402]. The anticorrosive effect of pyridinium [378,[403][404][405], pyrrolidinium [406][407][408], ammonium [9,[409][410][411][412] and phosphonium [409,413] based ionic liquids are also reported in the literature.…”

Spherical-micelle-driven deposition of high-speed impacting water droplets on superhydrophobic surfaces

“…Therefore, the complete spread and deposition of highspeed impacting droplets on a superhydrophobic surface can be realized by small spherical micelles, and not only by vesicles, 35,36,39 wormlike micelles, 37 and coacervates, 38 which overturns the conventional perceptions. 6,[21][22][23][24][25][26][27]…”

“…However, when imitating the spraying of plants, it is much more difficult to nd surfactants that completely inhibit the rebound and splash of high-speed droplets on superhydrophobic surfaces with a contact angle of pure water above 150°. 6,[21][22][23][24][25][26][27] In impact, the contact time of the droplets with the superhydrophobic surfaces is too short (∼2 ms) to allow the surfactants to move to the impact-created solid/ liquid interface, 28,29 and the retraction velocity of the impacting drop is enhanced by the reduced surface tension (g) according to the Kelvin-Helmholtz instability, k max z 2r a U r 2 /3g (r a is the air density). 30 According to the Weber number (We = rV 2 D/g) and Reynolds number (Re = rVD/h), increasing liquid viscosity 31,32 and decreasing dynamic surface tension 33,34 have long been considered to be two common strategies to promote deposition and spread.…”
