“…It is obvious that the addition of copper ions influences the characteristic absorption band. Such an effect was also described by Cabeza et al [52] and their investigation of ionic liquids containing complex metal thiocyanate anions. They found a double peak in the IR spectrum of copper thiocyanate ionic liquid at 2052 and 2069 1/cm.…”

“…In this work, we continue with the experimental study of ILs to which our groups have been devoted in the past years [ 12 , 13 , 14 ], and specifically, we focus on one of our lines of work dedicated to protic ionic liquids (PILs) [ 15 , 16 ], the usefulness of which has been widely tested. Within this class of materials, two representatives of the family of alkylammonium nitrates, ethylammonium nitrate (EAN) and propylammonium nitrate (PAN), have attracted great attention as a result of their multiple applications.…”

This paper presents a comprehensive study of two alkylammonium nitrate ionic liquids. As part of this family of materials, mainly ethylammonium nitrate (EAN) and also propylammonium nitrate (PAN) have attracted a great deal of attention during the last decades due to their potential applications in many fields. Although there have been numerous publications focused on the measurement of their physical properties, a great dispersion can be observed in the results obtained for the same magnitude. One of the critical points to be taken into account in their physical characterization is their water content. Thus, the main objective of this work was to determine the degree of influence of the presence of small quantities of water in EAN and PAN on the measurement of density, viscosity, electrical conductivity, refractive index and surface tension. For this purpose, the first three properties were determined in samples of EAN and PAN with water contents below 30,000 ppm in a wide range of temperatures, between 5 and 95 °C, while the last two were obtained at 25 °C. As a result of this study, it has been concluded that the presence of water is critical in those physical properties that involve mass or charge transport processes, resulting in the finding that the absolute value of the average percentage change in both viscosity and electrical conductivity is above 40%. Meanwhile, refractive index (≤0.3%), density (≤0.5%) and surface tension (≤2%) present much less significant changes.

“…Neat PVDF shows a single maximum degradation step at nearly 450 °C, which corresponds to the degradation of the carbon–hydrogen (C–H) and carbon–fluorine (C–F) bonds . For MIL/PVDF blends, two degradation steps are detected at ∼300 and 400 °C, respectively, except for the blend with 40 wt % MIL content, attributed to the degradation temperature of the MIL and the PVDF polymer, respectively. It is interesting to observe that the thermal degradation of PVDF in the MIL/PVDF blends has a strong shift to lower temperatures, slightly dependent on the MIL content, being the strong ion–dipole interactions between MIL and polymer responsible to this effect …”

“…Other absorption bands characteristic of the α-phase (796, 855, and 976 cm −1 ) and β-phase (1232 cm −1 ) are also identified in the spectra of Figure 3a. Furthermore, a vibration band at 2050 cm −1 that corresponds to the thiocyanate anion related to the C−N stretching 37 is also detected in the blends, which increases in intensity with increasing MIL loading within the polymer host.…”

Solid polymer electrolytes (SPEs) are required to improve battery safety through the elimination of the liquid electrolyte solution in current batteries. This work is focused on the development of a hybrid SPE based on poly(vinylidene fluoride), PVDF, and 1-butyl-3-methylimidazolium cobalt(II) isothiocyanate, [BMIM] 2 [(SCN) 4 Co] magnetic ionic liquid (MIL), and its battery cycling behavior at room temperature. The addition of MIL in filler contents up to 40 wt % to the PVDF matrix does not influence the compact morphology of the samples obtained by solvent casting. The polar β-phase of PVDF increases with increasing MIL content, whereas the degree of crystallinity, thermal degradation temperature, and mechanical properties of the MIL/ PVDF blends decrease with increasing MIL content. The ionic conductivity of the MIL/PVDF blends increases both with temperature and MIL content, showing the highest ionic conductivity of 7 × 10 −4 mS cm −1 at room temperature for the MIL/PVDF blend with 40 wt % of MIL. The cathodic half-cells prepared with this blend as SPE show good reversibility and excellent cycling behavior at different C-rates, with a discharge capacity of 80 mAh g −1 at a C/10-rate with a Coulombic efficiency of 99%. The developed magnetic SPE, with excellent performance at room temperature, shows potential for the implementation of sustainable lithium-ion batteries, which can be further tuned by the application of an external magnetic field.
