Outline of Final Research Achievements

Nanosheets have been introduced into various application fields due to their extreme two-dimensional structure and specific properties. In this study, we tried to develop a carbon dioxide selective membrane via a new separation mechanism by our techniques for controlling the nanosheet property and interlayer space. As a result, we succeeded in obtaining the selectivity of carbon dioxide opposite to the molecular size. It was suggested that the gas permeation through nanosheet film is driven by a anomalous mechanism different from the common-sense one because the selectivity didn’t depend on the surface state and layer spacing of the nanosheet thin film.

Academic Significance and Societal Importance of the Research Achievements

本研究により、ナノシートを用いた二酸化炭素分離膜の開発が進展した。ナノシートは極限に薄い「紙」であり、ナノシートから作製された分離膜は、従来の分離膜の性能を突破できる可能性を持つ。例えば本研究で得られた、分子のサイズに逆行した分離性のもその1つとみることができる。このように、本研究で得られた成果は、地球上の二酸化炭素削減に寄与し、自足可能な社会の発展に貢献できるものである。
