Rheological, Viscoelastic, and Dynamic Mechanical Behavior of ZnO-Filled and MA-Modified PP/SEBS Filaments for Fused Filament Fabrication

Abstract Immiscible polyolefin–elastomer blends often exhibit limited impact resistance and unstable melt-flow behavior due to weak interfacial adhesion and inefficient stress transfer between phases. These limitations are relevant for fused filament fabrication (FFF), where fila...

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–prop...
