“…Multiphase flow in porous media involves complex phenomena at the pore scale, often captured in terms of interfacial tension, contact angle, and capillary pressure. The accumulation of amphiphilic molecules, nanoparticles, or microorganisms at interfaces reduces the interfacial tension and affects the displacement of immiscible fluids, oil and gas recovery, CO 2 storage efficiency, and the environmental remediation of sites contaminated with either light or dense non-aqueous phase liquids. − Laboratory scale studies have successfully used zirconium dioxide ZrO 2 , titanium dioxide TiO 2 , silicon dioxide SiO 2 , and gold Au nanoparticles − to reduce the interfacial tension and change surface wettability. Yet, field-scale applications with synthesized nanoparticles remain hampered by high costs and potential environmental implications. ,, …”

The accumulation of amphiphilic molecules, nanoparticles, or microorganisms at interfaces has important implications for multiphase flow in porous media. We optimize the composition of stable organo-bentonite suspensions to enhance particle adsorption onto the oil–water interface. Then, we use the pendant drop method to explore time-dependent effects on surface tension and the consequences of contraction–expansion cycles. Brownian motion brings organo-bentonite particles to the oil–water interface where they adsorb and accumulate to reduce the apparent interfacial tension in time. The adsorption energy of platy organo-bentonite particles is significantly higher than the adsorption energy of spherical nanoparticles of the same volume. Then, a shell-like interface develops after particle jamming during droplet contraction, and further contraction leads to shell buckling and wrinkle formation (rather than desorption). The shell-like interface experiences an anisotropic stress field and cannot be described by the Young–Laplace equation. The evolution of interfacial tension during contraction and expansion shows strong hysteresis; furthermore, the results suggest that the number of adsorbed particles at the interface increases with the number of cycles. Natural clay nanoparticles can facilitate the development of cost-effective and environmentally friendly alternatives for field-scale applications.
