Design of Polymer-Based CO₂-Membrane Adsorbers for Carbon Capture

The data presented correspond to the experimental results reported in the publication “Design of Polymer-Based CO₂-Membrane Adsorbers for Carbon Capture”, which investigates the CO₂ capture performance of PDMAPAm and its diblock copolymer PDMAPAm‐b‐PMMA as membrane adsorbers for direct air capture, optimizing polymer composition and operating conditions through integrated adsorption and kinetic modeling under dry and humid environments.
