Exploring g-C₃N₄ as a green additive for biodegradable poly(butylene adipate-co-terephthalate) film with enhanced UV shielding and mechanical properties.

ABSTRACT: Typical small organic dyes exhibit excellent UV absorption capabilities and are commonly used as additives to shield plastic films from photoaging. However, their tendency to decompose easily and migrate rapidly within a polymer matrix limits their service life. Herein we prepared g-C₃N₄ nanosheets and fabricated g-C₃N₄/PBAT films to investigate the effects of g-C₃N₄ on UV shielding and plasticizing of a biodegradable PBAT film. Photophysical characterizations revealed that an improved UV light barrier performance was achieved on g-C₃N₄/PBAT films compared to pure PBAT. Furthermore, the photoaging results show that g-C₃N₄ can stably exist in the PBAT matrix, enabling the aged g-C
