Title:
SEPARABLE NANOSHEET AND PRODUCTION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2020/013215
Kind Code:
A1
Abstract:
The present invention provides a separable nanosheet which comprises a plurality of pseudo-polyrotaxane structures and in which the structures are not adherent to each other and are easy to separate. The separable nanosheet of the present invention comprises a plurality of pseudo-polyrotaxane structures each comprising first cyclic molecules and a linear molecule piercing the cavities thereof to form a clathrate, wherein the linear molecules include, as part thereof, first linear molecules having an ionizing group which ionizes in water or an aqueous solution.
