Poly(1-naphthylamine)-Reinforced Chitosan Films for Smart Packaging: Enhanced Mechanical, Morphological, and Antibacterial Properties.

ABSTRACT: The development of sustainable smart packaging materials has driven interest in chitosan (CS) films, reinforced with conducting polymers. In the present work, poly(1-naphthylamine) (PNA) was incorporated into CS matrix at low weight fractions (0.15-1.0 wt %) of PNA to produce composite films with enhanced mechanical and antibacterial performance. Characterizations using Fourier transform infrared, X-ray photoelectron, ultraviolet-visible, and fluorescence spectroscopy revealed significant interfacial interactions, as evidenced by distinct shifts in characteristic absorption peaks and the appearance of polaronic signatures. SEM and confocal imaging confirmed homogeneous PNA dispersion up to 0.5 wt %. The morphological transition from uniform network domains to the formation of agglomerates
