Membrane synthesis

Different applications require distinct membrane properties. In our laboratory, some processes utilize commercial membranes but some lines of research investigate the preparation of novel membranes with the desirable characteristics. Some examples are given below.

  • Biocatalytic omposite membranes for gas-liquid membrane contactors

Gas-liquid membrane contactor is one of the promising membrane separation technologies for carbon dioxide capture. When greener solvents are used, the carbon capture efficiency decreases significantly due to the slower kinetics of these greener solvents. Combining biocatalysts or enzymes with these green solvents could boost the carbon capture efficiency while allowing for conversion of capture carbon dioxide into useful products. In this research line, we are developing immobilization platform for biocatalysts or enzymes on the membrane surface by exploring the functionalities of : (1) biopolymers and metal-organic frameworks and (2) (poly) ionic liquids.

  • Composite and mixed matrix membranes for pervaporation/reactive pervaporation and water purification
  • Porous membranes for membrane crystallization
  • Supporter ionic liquid membranes for pervaporation/reactive pervaporation and liquid extraction

Tunability of physicochemical properties of ionic liquids makes them very interesting solvents. In supported ionic liquid membranes a small amount is immobilized in the membranes pores. The resulting membranes present high flux and good selectivity towards the target compounds.
