Nanocellulose Filled Bio-Based PVA/Chitosan Nanocomposites: Structure–Property Relationships toward Advanced Food Packaging Films
Journal: Preprints.org
Year: 2025

Biodegradable chitosan/poly(vinyl alcohol) (PVA) composite films were reinforced either with nanocrystalline cellulose (CNC) or nano-lignocellulose (NLC) and evaluated across a polyparametric design of five matrix ratios and three filler levels, for active food packaging applications. ATR-FTIR, DSC, XRD and SEM demonstrated that 1-5% nanocellulose load-ing induced a single relaxation temperature (Tg), homogenized the morphology and en-hanced the crystallinity of blend material, evidencing improv
