| Outline of Final Research Achievements |
This study clarified that the cellulose nanofibers prepared by aqueous counter collision (ACC-CNF) possess both hydrophobic and hydrophilic planes on a single nanofibril surface. Furthermore, it was indicated that this amphiphilic ACC-CNF was densely adsorbed at oil and water interface, which resulting in stable Pickering emulsion formation. The surface of ACC-CNF was acetylated only in oil phase of an emulsion system. The localized hydrophobic faces induced unique self-aggregation behavior of the modified CNF in water, which would be applied as a new approach to fabricate a material with higher-ordered hierarchical structure in an aqueous system.
