Complex between lignin and a Ti-based coupling agent

Jonas S. Rasmussen / Søren Barsberg / Claus Felby
Published Online: 2013-11-30 | DOI: https://doi.org/10.1515/hf-2013-0120


Durability, haptic, and optical appearance of wood are improved by coatings, which are nowadays prepared using environmentally compatible and less health-damaging materials. However, contemporary wood coatings have frequently a shortened service life compared to their traditional predecessors. New coating formulations would have a better performance if the adhesion to wood could be improved. In the present work, the chemical interaction between a titanium-based coupling agent, isopropyl triisostearoyl titanate (titanium agent, TA) and lignin has been studied by means of attenuated total reflectance-fourier transform infrared spectroscopy in combination with first principle predictions based on the density functional theory (DFT). In the infrared spectra, a new band at 1586 cm-1 was identified and the DFT predictions confirmed that the new band is because of the covalent bonds in the form of ether linkages between TA and lignin.

Keywords: attenuated total reflectance-Fourier transform infrared (ATR-FTIR); coating; complex formation; covalent bond; density functional theory (DFT); titanium coupling agent
