Research progress on lignin-based composite coatings for wood protection

Key Points

• Lignin-based composite coatings improve wood protection against environmental stressors and prolong lifespan.
• A specific metric indicates that durability of treated wood increases significantly compared to untreated samples.
• Research focuses on developing innovative biomaterials to enhance protective properties and sustainability.
• Findings suggest that lignin-derived coatings could offer an eco-friendly option for preserving wood against degradation.
