Conventional adhesives used in wood-based panels typically contain volatile organic compounds, including formaldehyde, which can potentially lower indoor air quality and damage human health. Lignin, a natural adhesive present wood, offers significant advantages over other materials due to its ready availability, renewable nature, rich aromatic rings, aliphatic hydroxyl groups, as well quinone groups. However, when modified an for panels, lignin suffers from poor water resistance formaldehyde...
