Composite films were developed using arecanut organic residue, an underexploited by-product, blended with polyvinyl alcohol (PVA) and chitosan. The films were synthesized through solvent casting and thermal curing, with experimental parameters systematically optimized. Physicochemical characterization confirmed successful integration of components and revealed structural properties. The catalytic efficiency of the films was evaluated in amide synthesis, a key reaction in pharmaceuticals. A blend of 1.5 g PVA, 0.3 g chitosan, and 1 mL arecanut residue achieved a 95 % yield in ester-amine reactions, attributed to synergistic interactions between the polymer matrix and reactive sites. The films exhibited excellent reusability, maintaining catalytic efficiency over three cycles. This study highlights the potential of arecanut residue-based composites as sustainable, efficient catalysts for industrially relevant transformations. 2025 Korean Physical Society Subject The topic of the resource Amidation; Arecanut organic residue; Chitosan; Green catalysis; Polymer film; PVA Publisher An entity responsible for making the resource available Elsevier B.V.
