Abstract:
In this paper, the influence of two types of imidazolium-based ionic liquids (ILs) on the properties of sycamore maple (Acer pseudoplatanus) veneers, at 25 0C, 60 0C and 80 0C has been studied by using contact angle measurements and Fourier transform infrared spectroscopy analysis. The measurements showed that wood wettabillity is increased by IL treatment. It has been determined that the ILs decrease the crystallinity and improve the flexibility of the cellulose matrix. Also, it has been determined that at 60 0C and 80 0C delignification of wood occurred, thus making the studied ionic liquids useful alternatives to traditional toxic and expensive reagents used in wood industry.
