| Outline of Final Research Achievements |
We have succeeded in measuring the change of orientation state by the flow of cellulose nanofiber (CNF) suspension. It can be predicted that the orientation state of CNF changes greatly in the flow where the flow changes drastically. Therefore, we first tried to measure the change of the orientation state of CNF at that point by using a flow channel where the shape of the flow channel suddenly changes. As a result, it was found that the orientation state of CNF can be successfully measured.
Next, in the simple shear flow field which is a simple flow, the orientation state of CNF was investigated. At this time, the effect of the shear rate, the size of the flow channel and temperature on the orientation state of CNF was investigated. As a result, it became clear that the orientation state greatly changes with shear rate and temperature.
