Research Abstract

Inorganic nanosheet is obtained by exfoliation of layered inorganic crystal. Structure of inorganic nanosheet in liquid would not be same as the one in dried state because of the soft nature of the nanosheet due to the high anisotropic ratio. We investigated the structure of a nanosheet in situ by dynamic light scattering and depolarized dynamic light scattering and we found that the most of the data can be reproduced by prolate model. The result suggests that the structure of the nanosheet in liquid is thoroughly different from the one in dried state.
