New Insights into PLA/PVA Blends: Unraveling the Composition–Structure–Property Relationship of Biopolymer Films Prepared by Single-Solvent Casting
Poly(lactic acid) (PLA) is a renewable and biodegradable polymer that has attracted considerable attention for sustainable packaging applications. However, its inherent brittleness limits its use in flexible films. In this study, PLA/poly(vinyl alcohol) (PVA) blend films were prepared by a single-solvent-casting rout a...
