Abstract

The rheological behavior of porous ionic liquids comprising ZIF-8 suspensions in two Newtonian ionic liquids - trihexyltetradecylphos- phonium bis(trifluoromethylsulfonyl)imide and tri- hexyltetradecylphosphonium chloride - exhibited distinct and unexpected differences. ZIF-8 suspensions in the bis(trifluoromethylsulfonyl)imide-based liquid showed Bingham behavior with a measurable yield stress, whereas those in the chloride-based liquid remained Newtonian, even at high solid volume fractions of up to 17.4%. Remarkably, the viscosities of these porous liquids were not significantly higher than those of the pure ionic liquids. While explaining these behaviours, we could elucidate how the stability and dynamic properties of porous ionic liquids are governed by the highly structured liquid phases, determined experimentally and using molecular dynamics simulations, and by the balance between particle-particle and ZIF-8-ionic liquid inter- actions, as evidenced by the heat effects measured during particle dispersion.

期刊介绍： ChemPhysChem is one of the leading chemistry/physics interdisciplinary journals (ISI Impact Factor 2018: 3.077) for physical chemistry and chemical physics. It is published on behalf of Chemistry Europe, an association of 16 European chemical societies. ChemPhysChem is an international source for important primary and critical secondary information across the whole field of physical chemistry and chemical physics. It integrates this wide and flourishing field ranging from Solid State and Soft-Matter Research, Electro- and Photochemistry, Femtochemistry and Nanotechnology, Complex Systems, Single-Molecule Research, Clusters and Colloids, Catalysis and Surface Science, Biophysics and Physical Biochemistry, Atmospheric and Environmental Chemistry, and many more topics. ChemPhysChem is peer-reviewed.
