| Research Abstract |
We have so far dispersed cellulose nanofibrils into water by using a surface carboxylation method of the nanofibrils, namely the TEMPO-mediated oxidation; the dispersed nanofibrils spontaneously align into a nematic-like order. In the present study, we have constructed a wide range of bulk materials, such as hydrogels, aerogels, and films, by controlling the integration mode of the self-aligned cellulose nanofibrils. These bulk materials consisted of aligned cellulose nanofibrils and exhibited outstanding properties.
