Gas transport properties of PEBAX(R)/Room Temperature Ionic Liquid gel membranes
Original language description
This work evaluates the possibility to tailor the gas separation properties of elastomeric block copolyamide membranes by means of room temperature ionic liquid (RTIL), based on the 1-n-alkyl-3-methylimidazolium cation. Polymeric gel membranes were prepared by adding from 20 to 80 wt.%of 1-butyl-3-methylimidazolium trifluoromethanesulfonate, [BMIM][CF3SO3] to Pebax_1657 and Pebax_2533. The effect of the ionic liquid on the microstructure, properties and performance of these membranes was discussed. Gaspermeation measurements show that the permeability and selectivity of Pebax_2533 are not notably affected by the addition of IL, whereas Pebax_1657 shows a significant increase in the gas permeability. At the same time the permselectivity of the latter for most gas pairs shows a slight decrease, in accordance with the typical Robeson trade-off behaviour. The combination of permeability and selectivity remains nevertheless interesting for applications involving for instance CO2 removal fr
