dc.description.abstract | [EN] Novel selective ceramic-supported thin polyimide films produced in a single dip coating step are proposed for membrane applications at elevated temperatures. Layers of the polyimides P84 (R), Matrimid 5218 (R), and 6FDA-6FpDA were successfully deposited onto porous alumina supports. In order to tackle the poor compatibility between ceramic support and polymer, and to get defect-free thin films, the effect of the viscosity of the polymer solution was studied, giving the entanglement concentration (C*) for each polymer. The C* values were 3.09 wt. % for the 6FDA-6FpDA, 3.52 wt. % for Matrimid (R), and 4.30 wt. % for P84 (R). A minimum polymer solution concentration necessary for defect-free film formation was found for each polymer, with the inverse order to the intrinsic viscosities (P84 (R) >= Matrimid (R) >> 6FDA-6FpDA). The effect of the temperature on the permeance of prepared membranes was studied for H-2, CH4, N-2, O-2, and CO2. As expected, activation energy of permeance for hydrogen was higher than for CO2, resulting in H-2/CO2 selectivity increase with temperature. More densely packed polymers lead to materials that are more selective at elevated temperatures. | es_ES |
