Lignin phosphorylation to enhance mechanical and physical properties and reduce formaldehyde emissions in plywood panels

Key Points

• The aim is to explore lignin phosphorylation for enhancing the properties of adhesives in plywood panels.
• Evaluated lignin's accessibility and molecular structure for adhesive use.
• Analyzed mechanical and physical properties of plywood panels with phosphorylated lignin.
• Measured formaldehyde emissions from plywood panels to assess environmental impact.
• Phosphorylated lignin improved mechanical properties of plywood panels.
• Significant reduction in formaldehyde emissions was observed compared to conventional adhesives.
• Enhanced barrier properties were reported in modified plywood panels.
