This work was aimed at evaluating adsorption of water molecules onto membrane surfaces modified by sulphonamide derivates. Controlling interfacial forces at the membrane-feed interface were assessed by combining experimental and theoretical studies. The phenomena experimentally observed were also interpreted by using quantum-chemical and dynamic approaches in order to correlate the membrane affinity to water with the availability and accessibility of polar moieties, enabling to form intermolecular interactions such as hydrogen bonds.

Abstract
This work was aimed at evaluating adsorption of water molecules onto membrane surfaces modified by sulphonamide derivates. Controlling interfacial forces at the membrane-feed interface were assessed by combining experimental and theoretical studies. The phenomena experimentally observed were also interpreted by using quantum-chemical and dynamic approaches in order to correlate the membrane affinity to water with the availability and accessibility of polar moieties, enabling to form intermolecular interactions such as hydrogen bonds.File in questo prodotto:
