Solvent-Driven Interfacial Regulation of Lignin/PCL Composites Using γ-Valerolactone
The intrinsic incompatibility between lignin and biodegradable polyesters remains a key barrier to the development of high-performance biobased composite films. We propose a γ-valerolactone (GVL)-enabled strategy to regulate interfacial interactions between alkali lignin (AL) and polycaprolactone (PCL) through cross-...
