Functionalization of Nano Cellulose Materials

Innovating Thermal Performance of Nanocellulose

SDGs / Cellulose nanofiber (CNF) / Hierarchical structure / Control of CNF alignment / Development of novel materials with high-performance thermal and electrical properties

Cellulose nanofibers (CNFs), wood-derived new sustainable materials, have been attracting attention in recent years. We are working on the development of high-performance CNF materials. We aim to improve the physical properties of CNF materials by engineering the CNF assembly and interfacial structure.
