Ionic liquid application for wood-based materials

Research output: Chapter in Book/Report/Conference proceedingConference article in proceedingsScientificpeer-review


All-cellulose materials have novel properties to compensate for the use of conventional package materials. We studied the conversion of woodfree paper into plastic-like material using the ionic liquid (IL) 1-Ethyl-3-methylimidazolium acetate ([EMIM][OAc]). By changing the treatment intensity, IL partially or fully dissolves the cellulose component. Thus paper can be converted into transparent film or composite materials. Additional chemical crosslinking for IL-treated papers gave higher stiffness and less water absorption. We further applied IL-treatment for sawdust to make partileboard and strand.
