Transport of water in soft confinement: influence of hydrostatic pressure and mechanical stress
Transport of water in soft porous materials is relevant to a broad range of applications but remains unclear in many aspects because of several effects that have to be taken into account: surface chemistry, diffuse boundaries and deformations or mechanical effects. In the proposed study, we plan to experimentally investigate the interplay between mechanical deformation, structure and transport. On the selected sample of heterogeneous hydrophobicity (PIM, Intrinsic Microporosity Polymer), we will characterize the collective and individual dynamics of confined water on a complementary timescale to previous TOF measurements, under different mechanical loads and hydraulic pressures. For this purpose, we require 3 days on IN16B, 5 days on WASP and 1 day on IN15.
