摘　　要：Furfurylation,a renowned chemical modification technique,uses furfuryl alcohol to enhance the properties of wood.This technology can be further refined by incorporating renewable tannins,which promote cross-linking with furfuryl alcohol.This study investigates the effects of furfurylation and tannin-modified furfurylation on the physical and mechanical properties of tropical Gmelina wood(Gmelina arborea Roxb.).Experiments involved impregnating Gmelina wood with aqueous solutions of furfuryl alcohol(FA)at 40%and 70%concentrations,as well as FA-tannin combinations(FA 40%-TA and FA 70%-TA),followed by polymerization at 103℃.The results demonstrated that both FA and FA-tannin treatments significantly improved the wood’s physical and mechanical properties.Notably,FA-tannin treatments achieved anti-swelling efficiency comparable to FA alone.However,the addition of tannins(FA 70%-TA)enhanced leaching resistance by up to 47%,contributing to a more environmentally sustainable modification process.Mechanically,the inclusion of tannins in FA 70%-TA slightly increased the modulus of elasticity(14%~8732 kg/cm^(2))and the modulus of rupture(9%~40.9 kg/cm^(2)).Furthermore,the tannin addition imparted a darker color to the modified wood,enhancing its aesthetic appeal.This study highlights the potential of tannin-modified furfurylation to advance wood modification technology,combining improved performance with environmental benefits.
