Abstract
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-linking network formation. GVL serves as a dissolution and purification medium, removing insoluble impurities and aggregates while promoting homogeneous lignin dispersion. A flexible cross-linked network is constructed via epoxy ring-opening reactions, enhancing interfacial adhesion and modulating chain mobility. The resulting films exhibit balanced mechanical strength (14.64 MPa) and ductility (1415% elongation), together with ultraviolet shielding, photothermal conversion (∼25 °C), and tunable gas/water vapor transport (O2/CO2 ≈ 1.2; WVTR < 100 g/(m2·day)). This study provides fundamental insights and a scalable pathway for engineering biodegradable composite films.
The development of renewable polymer networks combining mechanical performance with repairability and reprocessability is important for advancing sustainable materials. In this study, chitosan-dialdehyde lignin (Ch-DAL) bioplastic films were fabricated through dynamic Schiff base cross-linking between tartaric acid-pro...

Designing sustainable polymer materials that combine mechanical robustness with recyclability remains a significant challenge. Here, we report a cellulose-based Diels–Alder (DA) cross-linked network that integrates structural strength, thermoreversible recyclability, and tunable biodegradability. Cellulose was functi...
Starch/poly(butylene adipate‐co‐terephthalate) (PBAT) composite films containing dual silicate fillers were fabricated by extrusion blowing for biodegradable modified‐atmosphere packaging (MAP). The combination of diatomite, kaolin and zeolite was associated with a filler‐mediated interfacial network that enhanced...
The development of sustainable coatings that combine reprocessability with active functionalities remains a central challenge for the composites sector. In this work, a healable, electrically conductive coating was formulated using epoxidized castor oil (ECO) as a bio-based matrix, dibutyl phosphate (DBP) as a transest...

Poly(vinyl alcohol) (PVA) is a promising biodegradable polymer; however, its reliance on petroleum and incompatibility with raw lignin additives hinder sustainable PVA composite development. In this study, mechanically robust PVA/functionalized acid-soluble lignin (fLGAS) composite films were developed by means of aque...
