    Swelling of Polymeric Membranes in Room Temperature Ionic Liquids

  • Original language description

    This research work demonstrates how an optical technique, developed for studying the process of polymer swelling, is able to produce highly reproducible data of swelling of dense polymeric membranes exposed to liquid mixtures. This technique was appliedfor studying the swelling process of different polymeric membranes, from proton conducting polymers (Nafion) to non-charged hydrophobic polymers, such as a polyurethane-polybutadiene elastomer (PU/PBDO), polydimethylsiloxane (PDMS) and polyvinylidene fluoride membrane (PVDF). Room temperature ionic liquids (RTILs) were chosen as solvents to be studied, due to the growing interest of using their unique physico-chemical properties in hybrid membrane processes. The results obtained show that the techniquedeveloped allows for studying the swelling and "deswelling" of polymeric membranes even when anisotropic phenomena take place. These results are discussed and interpreted from the perspective of the nanoscale properties of the polymers.

    Botnání polymerních membrán v "room-temperature" iontových kapalinách

  • Czech description

    Práce publikuje výsledky měření botnání neporézních polymerních membrán v kapalinách nově vyvinutou optickou metodou, u které je prokázána vysoká míra spolehlivosti a přesnosti. Byly studovány jak mebrány iontoměničové (Nafion) tak hydrofobní (polyurethane-polybutadiene elastomer (PU/PBDO), polydimethylsiloxane (PDMS) and polyvinylidene fluoride membrane (PVDF)). Iontová rozpouštědla kapalná při pokojových teplotách byla vybrána kvůli rostoucímu zájmu o jejich specifické fyzikálně-chemické vlastnosti, které jsou zajímavé z hlediska membránových hybridních procesů.
