Outline of Final Research Achievements

The tensile strength of single cellulose nanofibers was was estimated based on a model for the sonication-induced fragmentation of filamentous nanostructures. The mean strength of wood-derived cellulose nanofibers was about 3 GPa. The highly crystalline, thick tunicate cellulose nanofibers exhibited higher mean strength of 6 GPa and the maximum strength of 10 GPa. The strength values estimated here are comparable with those of commercially available multi-walled carbon nanotubes.
