“…According to the HSP concept, the total solubility parameter (δt) of an IL can be divided into partial solubility parameters, namely, polar (δP), hydrogen bonding (δH) and dispersion (δD) [39,40,41]:δt2=δD2+δP2+δH2…”

The physicochemical properties of four 1-alkyl-3-methylimidazolium bromide ([CnC1im]Br, n = 5, 6, 7, 8) ionic liquids (ILs) were investigated in this work by using inverse gas chromatography (IGC) from 303.15 K to 343.15 K. Twenty-eight organic solvents were used to obtain the physicochemical properties between each IL and solvent via the IGC method, including the specific retention volume and the Flory–Huggins interaction parameter. The Hildebrand solubility parameters of the four [CnC1im]Br ILs were determined by linear extrapolation to be δ 2 ( [ C 5 C 1 im ] Br ) = 25.78 (J·cm−3)0.5, δ 2 ( [ C 6 C 1 im ] Br ) = 25.38 (J·cm−3)0.5, δ 2 ( [ C 7 C 1 im ] Br ) =24.78 (J·cm−3)0.5 and δ 2 ( [ C 8 C 1 im ] Br ) = 24.23 (J·cm−3)0.5 at room temperature (298.15 K). At the same time, the Hansen solubility parameters of the four [CnC1im]Br ILs were simulated by using the Hansen Solubility Parameter in Practice (HSPiP) at room temperature (298.15 K). The results were as follows: δ t ( [ C 5 C 1 im ] Br ) = 25.86 (J·cm−3)0.5, δ t ( [ C 6 C 1 im ] Br ) = 25.39 (J·cm−3)0.5, δ t ( [ C 7 C 1 im ] Br ) = 24.81 (J·cm−3)0.5 and δ t ( [ C 8 C 1 im ] Br ) = 24.33 (J·cm−3)0.5. These values were slightly higher than those obtained by the IGC method, but they only exhibited small errors, covering a range of 0.01 to 0.1 (J·cm−3)0.5. In addition, the miscibility between the IL and the probe was evaluated by IGC, and it exhibited a basic agreement with the HSPiP. This study confirms that the combination of the two methods can accurately calculate solubility parameters and select solvents.

The solubility parameters of four ionic liquids (ILs), 1-ethyl-3-methylimidazolium methyl sulfate ([EMIM][MeSO4]), 1-butyl-3-methylimidazolium methyl sulfate ([BMIM][MeSO4]), 1-hexyl-3-methylimidazolium methyl sulfate ([HMIM][MeSO4]), and 1-octyl-3-methylimidazolium methyl sulfate ([OMIM][MeSO4]), were estimated using two complementary methods. The first is an inverse gas chromatography (IGC) method, which determined the Hildebrand solubility parameters of four ILs based on a series of formulaic calculations. The second is the Hansen solubility sphere method, which determined the Hansen solubility parameters (HSPs) of the four ILs based on solubility testing of four ILs in 30 pure solvents. The results showed that the Hansen solubility sphere method provides higher values of the solubility parameters, while the IGC method presents lower values. In addition, the miscibilities of ILs in various solvents were evaluated by the method of IGC, and the results exhibit good agreement with those derived from the Hansen solubility sphere method. It is confirmed that the IGC and Hansen solubility sphere methods can be used to determine the solubility parameters of the ILs and were useful for solvent selection.

“…In the last seven years, few works have been published with Somasif ME-100 synthetic mica [23,24] . The amount of articles is even smaller when it comes to the use of Somasif ME-100 with polymers [15,[25][26][27][28][29][30][31][32][33][34] . This fluoromic was little explored in NBR, which is a very important rubber for the industry, and only one article was found in the literature that correlates Somasif ME-100 with NBR [16] .…”

Nitrile rubber (NBR) nanocomposites with different contents of synthetic Somasif ME-100 mica (sodium-fluorohectorite) were obtained by melt compounding using a Semi Efficient curing system. The effect of curing on the nanocomposties was evaluated through rheometric properties, crosslink density (CLD) and mechanical properties. The ME-100 mica dispersion in NBR was assessed by transmission electron microscopy (TEM), the Payne effect and thermodynamic properties (ΔS and ΔG). Both the curing parameters and CLD pointd out that the addition of ME-100 directly affects crosslinks formation. It could also be observed that the nanofiller dispersion state is complex, exhibiting exfoliated and agglomerated structures (TEM); besides, agglomerations rose linearly as the nanofiller was added (the Payne effect). Notwithstanding these findings, and on the basis of unfilled formulations, NBR20 nanocomposite showed improvement in mechanical properties (tensile and tear strengths) which suggests that ME-100 might be considered a semi-reinforcing filler.
