Description

<p>Cellulose nanofibers (CNFs), which is crystalline cellulosic fibers of 3-100 nm in width, is a hopeful advanced material. However, increasing thermal stability is an issue for application of CNFs. The author has reported that thermal-degrading temperature of CNF was increased by biomass-degrading enzymatic treatment, such as a hemicellulase. The properties of their sheets were unknown. The basic sheet properties of enzyme treated CNF were investigated in this study. The tensile strength of CNF sheets was decreased by enzymatic treatment. On the other hand, the contact angle of their sheets was increased. These results indicate that surfaces of CNFs slightly increased hydrophobicity by biomass-degrading enzymatic treatment.</p>
