Forced water intrusion into deformable hydrophobic nanopores
Water in hydrophobic confinement is of general interest for industrial applications as well as the understanding of biological matter and more generally in the field of soft condensed matter. Ordered hydrophobic nanoporous materials provide well defined geometries to study water in hydrophobic confinement. While water confined in hydrophilic nanopores has been extensively studied, water confined in highly hydrophobic nanopores has been rarely considered especially because of the high pressure required to fill hydrophobic nanopores. The goal of this proposal is to quantify the deformation of hydrophobic grafted MCM41 nanoporous material upon water forced intrusion. These deformation measurements will provide information on the impact of confined water and interfacial energy on the mechanical properties of the confining material, a better understanding of the mechanics at pore scale and intrusion mecanism.
