Sycamore Maple: Wood Properties and Lignin-Based Adhesive

This lecture covers the botanical features, growth conditions, and wood properties of the Sycamore Maple tree, including its density, hardness, and breaking stress. It also discusses the elemental composition and ash content of organosolv lignin, as well as the preparation and characterisation of a lignin-based non-isocyanate polyurethane adhesive for wood. The lecture delves into the chemical reactivity of lignins and the development of material applications, emphasizing the importance of a target-driven chemical functionalization. It presents detailed data on the structural features of Kraft lignin and the mechanical properties of the lignin-based adhesive, highlighting its satisfactory performance in bonding wood panels.
