Outline of Final Research Achievements

An ionic liquid, 1-butyl-3-vinylimidazolium iodide ([BuVyIm]I), was synthesized, and leaching and decay resistance after polymerization within wood were studied. Treated wood specimens of Cryptomeria japonica with 10% and 30% concentration of [BuVyIm]I were evaluated with leaching tests for 10 times of wash with distilled water and dry and decay resistance for 12 weeks with brown rot fungi Fomitopsis palustris. The efficiency of a crosslinking agent TMPTA was also evaluated. The decay test of these specimens showed that the mass loss of wood specimens treated with 10% concentration of [BuVyIm]I diluted with distilled water was less than 3%. The mass loss of specimens treated with 30% concentration of [BuVyIm]I with 3% of TMPTA and mixed liquids with water and ethanol (1:1) was also below 3% of mass loss. From these result, it was found that the treated wood specimens with 10% of [BuVyIm]I had the potential for decay resistance.
