Membranes have been synthesized from new polymer materials. The latter has a two-dimensional structure that makes the polymer extremely porous at the molecular level. Thus, molecules are “sorted” according to their size or solubility.
Already used in various industrial processes such as the production of drinking water from saltwater, or dialysis in the medical field, these membranes are constantly evolving to improve the profitability and efficiency of molecular separation. To guarantee maximum productivity of this process, it is necessary to combine a high microporosity and a certain rigidity which gives the membranes a high permeability. This concept with low environmental impact is therefore very promising for solving greenhouse gas problems because it could filter the CO2 molecules contained in the atmosphere.
