Abstract EN
To understand the swelling behavior of cellulose nanofibril (CNF) films, the dimensional variation of untreated and phenol formaldehyde modified CNF (CNF/PF) films soaked in distilled water was examined in situ with microscopic image recording combined with pixel calculation.
Results showed that a dramatic thickness increase exhibited in both CNF and CNF/PF films, despite being at different swelling levels.
Compared to thickness swelling, however, the width expansion for these films is negligible.
Such significant difference in dimensional swelling for CNF and PF modified films is mainly caused by nanofibril deposition and their mesostructure.
However, addition of PF modifier has a positive effect on the constraint of water absorption and thickness swelling, which is strongly dependent on PF loadings.
