Claim 0:
1. A gas filter, comprising:
a plurality of multilayered membranes fixed inside a cell;
wherein each multilayered membrane of the plurality of multilayered membranes comprises:
a first layer, comprising at least 50 wt. % of one or more sulfone-containing polymers;
a second layer, comprising at least 50 wt. % of one or more polyamides comprising, in condensation polymerized form, an aliphatic diamine and an aromatic dicarboxylate; and
at least one carbide-derived carbon (CDC) nanoparticles selected from the group consisting of SiC, Fe3C, WC, Ti3SiC2, ZrC, B4C, TaC, Mo2C, and TiC-derived nanoparticles, wherein the CDC nanoparticles are embedded in the second layer in an amount of from 0.005 to 0.5 wt. %, based on a total weight of the second layer,
wherein the first layer directly contacts the second layer.
