講演要旨

This research investigates the effects of cellulose nanofiber (CNF) loading and residual moisture on the crystallization, structural development, and mechanical properties of poly(vinyl alcohol) (PVA)/CNF nanocomposite films. Using thermal analysis, X-ray scattering, spectroscopy, microscopy, and mechanical testing, it was found that low CNF contents promote PVA crystallization by acting as nucleating agents, whereas higher CNF contents
suppress crystallization by restricting polymer chain mobility.
Residual moisture was also shown to significantly influence crystallization and stiffness. These findings provide new insights into the relationship between nanostructure, crystallization, and mechanical properties, offering useful guidelines for designing high performance, sustainable polymer nanocomposites.
