Gas transport properties of PEBAX(R)/Room Temperature Ionic Liquid gel membranes

Popis výsledku v původním jazyce

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
