Preparation of composite poly(ether block amide) membrane for CO2 capture

Preparation and characterization of CO2‐selective Pebax/NaY mixed matrix membranes

“…Polyether‐block‐amide (Pebax) is a thermoplastic elastomer copolymer constructed by flexible polyether segments of polar group (such as PEO, PTMO) and rigid aliphatic polyamide segments (PA6, PA12) . It has proved that Pebax is a very promising membrane material for CO 2 removal from other nonpolar gas components (i.e., N 2 , H 2 , CH 4 , and acid gas), due to its superior physical properties such as mechanical, thermal stability, durability, high flexibility, and excellent selectivity to polar gases like CO 2 .…”

Synthesis of a PEBAX-1074/ZnO nanocomposite membrane with improved CO 2 separation performance

“…Since nanoparticles possess specific physical and chemical properties compared to bulk materials, they are utilized in synthesis of nanocomposite membranes to make favorable structures. Addition of inorganic particles in the polymer matrix can also influence permeability and consequently CO 2 /CH 4 and CO 2 /N 2 selectivity values of the membranes [10,11] . Incorporation of inorganic phase into the polymer matrix can also improve chemical and thermal stability of polymers [12] .…”

Application of polyhedral oligomeric silsesquioxane to the stabilization and performance enhancement of poly(4‐methyl‐2‐pentyne) nanocomposite membranes for natural gas conditioning

“…On the other hand, these components are valuable feedstocks and precious fuels that should be recovered for economic reasons from natural gas and flue gas . Despite cryogenic distillation, which has traditionally been used for the separation of natural gas components, the application of polymeric membrane processes reduces the total capital investment, operational cost, emissions, and energy consumption …”
