Water dynamics in mesopores with a periodic distribution of ionic surface charge
The dynamics of liquid water in spatially confined geometry has been extensively studied, especially using mesoporous silica as a model system. According to the abundant QENS literature, it appears that the chemical nature of the surface of nanoporous materials can be envisioned as a driving parameter of water dynamics. Our aim is to make use of this phenomenon in order to tune the interfacial mobility of nanoconfined water from a spatially controlled activation/deactivation of the surface electrostatic charge of the mesopores. The rationale of the project relies on our capability to design nanochannels that exhibit a periodic succession of neutral/charged nanodomains comprising inorganic and organic cationic units, which are perfectly localised along the main pore axis at the molecular scale. Our measurements at IN16B will complement those data to be acquired during an already scheduled beamtime at SHARP.
