Gas Transport Properties of PEBAX/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. DSC analysis showed a gradual decrease of the melting point of the polyamide (PA) blocks in the gel with a decrease in the corresponding melting enthalpy and a complete disappearance of the crystallinity of the polyether (PE) phase with increasing IL content in the case of Pebax 1657. In Pebax 2533 there is virtually no shift in the peak positions and both crystal phases remain present in the gel, indicating effective phase separation between the crystalline fraction of the polymer and the
