Abstract

In recent years, the development of utilization technology of woody biomass for energy and material has attracted much attention. The main component of wood is cellulose. The nature of cellulose in wood is an assembly of cellulose molecules called the cellulose microfibril. Cellulose nanofibers are bundles of cellulose microfibrils and have the feature of high strength and lightweight.<BR>In this study, we have used cellulose nanofibers obtained from wood as a core material, and have developed the nanofiber reinforced composite and the pretreatment for enzymatic saccharification (bioethanol production). Cellulose nanofibers can be directly prepared from wood by the combined process of wet-milling and hydrothermal treatment (hydrothermal-mechanochemical treatment). The nanofibers have a very large surface area. Therefore, the enzyme readily accesses the cellulose molecules and saccharify.<BR>In the production of nanofibers, water is essential. Thus, the drying process is required in the compounding of nanofiber with resin. However, the nanofibers tend to aggregate each other. We tried several methods to prevent aggregation of nanofibers in the composite. As a result, the masterbatch method was effective in dispersing of the nanofibers. The masterbatch was prepared by directly blending the nanofiber slurry into the low melting point polyolefin, evaporating water. The nanofiber-polypropylene composite containing just 1 wt % nanofiber showed high strength and high elongation.
