Outline of Final Research Achievements

Composites of cellulose and inorganic silica were investigated for the purpose of developing new hybrid material based on cellulose. Cellulose /LiCl/dimethylacetamide solution and alkoxysilanes were blended to prepare cellulose-inorganic hybrid films. The mechanical properties of the hybrid films have improved. Moreover, high-performance hybrid materials of the cellulose sheet were yielded by surface coating of the cellulose sheet with silanes. These results would be the core knowledge for developing cellulose-inorganic hybrid materials that can control performance using cellulose and alkoxysilanes.
