Web16 okt. 2012 · It is also shown that drop spreading on hydrophilic and superhydrophobic surfaces occurs with different time scales. Finally, if the surface is superhydrophobic, eventual impalement, i.e., transition from Cassie to Wenzel wetting state, which might occur in the vicinity of the drop impact area, does not influence drop maximum spreading. Web10 apr. 2024 · Recently, the relaxation behaviors of regenerated cellulose fibers induced by water have been studied. These explorations suggest that the glass transition temperatures of 513–552 K in a dry state are shifted to room temperature by interaction with water. This water-induced behavior may also occur in the transitions of natural cellulose fiber. In this …
