Outline of Final Research Achievements |
This study aims at exploring the fundamentals of the originally developed "three-component separation technology of wood”. Specifically, the influence of carbon numbers in alkylation reagents and that of plant species, conifers, hardwoods, and herbaceous plants on separation of three components were investigated by detailed chemical structure analysis using NMR and by thermal property analysis using DSC. The results revealed that differences in molecular weight and the hydrophilic-hydrophobic balance of the molecules had a significant effect on the separation of cellulose, hemicellulose, and lignin. It was also revealed that a small amount of mixture, which can only be obtained from compounds derived from wood, has a positive effect on thermal and mechanical properties. Furthermore, we succeeded in synthesizing a variety of functional materials by taking advantage of the characteristics of wood components including bark-extracted components.

Academic Significance and Societal Importance of the Research Achievements |
脱炭素社会の構築は喫緊の課題であり、再生可能資源である植物材料の重要性が高まっている。石油資源を代替すべく、生分解性を有する植物資源の有効活用に関する研究を推進できれば、海洋プラスチック問題など環境汚染問題の解決にも繋がり社会的意義が大きい。 木材から一挙に3種類の高分子誘導体を合成する方法を様々な植物種に適用できる事を明らかにした点、異なる植物種から得られる材料の物性に明らかな違いが発現した点、本法でのみ得られる物性値を有する材料が得られた点などが、本研究の特に重要な研究成果である。この研究は、バイオリファイナリー研究分野に大きなインパクトを与えると考えており学術的意義が大きい。
