This study systematically investigates the structural, thermal, mechanical, and gas separation properties of hydrogen-bond (H-bond) induced Pebax/epigallocatechin gallate (EGCG) membranes, emphasizing role EGCG as an H-bond inducer. Pebax ® 1,657 membranes were fabricated via solution casting using a mixed solvent system water ethanol, with incorporated at varying concentrations (0–20 wt%) to assess its impact on membrane properties. The hydroxyl-rich structure facilitates robust hydrogen-bonding interactions matrix, forming transiently crosslinked structure. strong interaction reduces matrix’s free volume alters microstructure by decreasing crystalline domain size polyamide (PA) enhancing exposure amorphous poly (ethylene oxide) (PEO) chains in Pebax. At optimal loading 5 wt%, exhibited CO 2 permeability 60.2 ± 1.1 Barrer /N selectivity 49.6 0.8, representing 33% increase compared pristine membranes. These performance enhancements are attributed reduction fractional (FFV) due H-bond-induced structural modifications increased availability PEO chains, which enhance diffusivity solubility selectivity, respectively. Moreover, mechanical testing demonstrated that wt% EGCG-incorporated maintains integrity, preserving tensile strength while slightly improving elongation break. Molecular dynamics (MD) simulations FFV solubilities corroborate experimental observations, offering insights into mechanisms underlying improved performance. results highlight effective inducer for tuning achieving balance between stability efficiency loading. provides foundation scaling up all-organic Pebax/EGCG high-performance structures, presenting promising approach industrial carbon capture applications.
