Structure–Property–Durability Relationships in Grape-Derived Pectin/Kraft Lignin Films Before and After Accelerated UV Aging
Pectin films are promising renewable materials for biodegradable coatings; however, their high hydrophilicity and limited resistance to ultraviolet (UV) radiation restrict practical applications. This work investigated the influence of kraft lignin (0–5 wt%) on the structure–property relationships of grape-derived pect...
