Local grafting heterogeneities control water intrusion and extrusion in nanopores [PDF]

open access: yesCommun Mater 5, 100 (2024), 2023
Hydrophobic nanoporous materials can be intruded by water only by exerting an external action, typically increasing pressure. For some materials, water extrudes when the pressure is lowered again. Controlling intrusion/extrusion hysteresis is central in a number of technological applications, including materials for energy applications and for high ...
