| Outline of Final Research Achievements |
We established a method for highly accurately evaluation of the shape of nanomaterials that have an anisotropic shape in liquid phase. Specifically, we verified the classification accuracy based on the length and shape of anisotropic materials such as nanocellulose by the field-flow fractionation method, and further analyzed the classified samples by depolarized dynamic light scattering method to evaluate translational/rotational diffusion coefficients. After the comparison between the results by depolarized dynamic light scattering and electron microscope, the measurement accuracy of anisotropic nanomaterials in liquid phase were verified. The well establishment of a length / shape measurement platform for anisotropic nanomaterials was achieved.
