This study developed biodegradable PBAT/lignin composite films reinforced with silane-modified silica nanoparticles, aiming to improve mechanical strength while maintaining UV-blocking properties useful for agricultural film applications. Developing high-performance biodegradable agricultural plastics is important for reducing the plastic mulch that is a major source of microplastic contamination in farmland soils.
Conversion of Cellulose and Lignin Residues into Transparent UV-Blocking Composite Films
Researchers developed UV-blocking composite films by chemically converting cellulose and lignin residues from three biomass sources (aspen wood, poplar wood, and corn stover) via a dissolution-regeneration process, assessing their UV-blocking performance as a sustainable alternative to petrochemical plastic films. Results showed that all three lignin residue types enhanced the UV-blocking properties of the composite films, supporting their potential in functional biorefinery-integrated packaging.
