    Triboelectric and Hydrophobic Characterization of Functionalized Lignocellulosic Materials; [Triboelektrična i hidrofobna svojstva funkcionaliziranih lignoceluloznih materijala]

    In the development of sustainable products, lignocellulosic materials with hydrophobic properties can be functionalized and used as reinforcement, especially in bio-composite materials, as well as in various applications such as packaging, water-repellent and self-renewing materials. This study is aimed to improve the surface properties and triboelectric properties of wood materials. Functionalized wood veneers were prepared by impregnating 3 different wood veneers (beech, mahogany and oak) with 5 different chemical solutions (cationic cellulose, cationic starch, polyethyleneimine, sodium alginate and carboxymethyl cellulose). Structural characterization of the functional wood materials obtained was investigated by Fourier-transform infrared spectroscopy (FT-IR) technique, wettability and surface properties were examined by contact angle measurements, and mor-phological properties were examined by scanning electron microscopy (SEM). The triboelectric properties of the devices prepared using functionalized wood materials were investigated. As a result, it was determined that the hydrophobic properties of wood materials were improved and showed triboelectric properties. It demonstrates that functionalized wood materials can be used to power low-power electronic devices. © 2023 by the author(s). Licensee Faculty of Forestry and Wood Technology, University of Zagreb.
