From polyamide microplastic waste to UV-blocking food packaging

Caption

THIS SCHEMATIC ILLUSTRATION SHOWS THE CONVERSION OF POLYAMIDE MICROPLASTIC WASTE INTO DEFECT-ENGINEERED CARBON QUANTUM DOTS (DEPA-CQDS), THEIR INCORPORATION INTO TRANSPARENT AND FLEXIBLE PVA FILMS, AND THEIR APPLICATION AS UV-BLOCKING FOOD PACKAGING. THE RESULTING CQD–PVA FILMS COMBINE UV SHIELDING, LUMINESCENCE, AND OPTICAL TRANSPARENCY, HELPING REDUCE UV-INDUCED FRUIT DETERIORATION AND EXTEND GRAPE SHELF LIFE.
