Techniques such as UV–visible spectroscopy, Fourier transform infrared spectroscopy (FTIR), dynamic light scattering (DLS), and transmission electron microscopy (TEM) were employed to analyze the ILs-MWCNT composites. The results indicate that MWCNT concentration significantly affects their interaction with ILs at 0.025 mg/mL of fCNTs being optimal for imidazolium-based ILs. Higher IL concentrations (0.5 and 1.0 mg/mL) were found to be less effective. Imidazolium-based ILs were more effective than cholinium-based ILs in dispersing of fCNTs, due to cation–π or CH–π interactions between imidazolium cations and the π-electron network of fCNTs. The formation of nano-IL-based composites was confirmed by a new absorption band around 225 nm in the UV–visible spectra. The stability in the absorbance peak suggests that the interaction between the ILs and fCNTs forms a stable complex that does not undergo significant changes or degradation for long-time, which makes them suitable for long-term use in various technological and industrial applications. This finding highlights the robustness of the IL-MWCNT interaction and underscores the potential of these materials for applications requiring stable and durable nanomaterial dispersions.

The binding constant and partition coefficient values indicate a more favorable interaction of DMASP with cationic surfactant Cetyltrimethylammonium bromide (CTAB) compare to the anionic surfactant Sodium dodecyl sulfate (SDS).

At present, the selection of force field models for H<sub>2</sub>O/CO<sub>2</sub> mixtures are rather complicated, chaotic and inconsistent, the calculation of each parameter necessitates the use of one force field model. There is no universal force field model to calculate and conduct thermophysical property of H<sub>2</sub>O/CO<sub>2</sub> at one time in a wide range of temperature within SCW. In this paper, heat capacity, viscosity and thermal conductivity of multiple mixtures in supercritical and near-critical water (575 K–1075 k) are first investigated via a novel common force field model with molecular dynamics (MD) simulations. The effects of different factors including the pressure, temperature and CO<sub>2</sub> mass fraction on thermophysical properties of H<sub>2</sub>O/CO<sub>2</sub> at a wide range of temperature were first analyzed and conducted in detail.
