Eco-friendly enhancement of optical and structural properties in polyvinyl alcohol films via eggplant peel dye doping

Abstract This study presents an eco-friendly strategy to enhance the optical and structural properties of polyvinyl alcohol (PVA) films through doping with eggplant peel dye (EPPD), a natural pigment extracted from agricultural waste via a green aqueous synthesis (~ 33% yield from 30 g of peel). EPP...
