Japanese Patent JP2018002885
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a hydrogen gas barrier film having excellent barrier properties against hydrogen gas.SOLUTION: A hydrogen gas barrier film according to an embodiment mainly comprises anion-modified cellulose nanofibers having an anionic group. In a preferred embodiment, the hydrogen gas barrier film is obtained by preparing a cellulose nanofiber dispersion in which anion-modified cellulose nanofibers having an anionic group are dispersed in a dispersion medium comprising water and a hydrophilic liquid medium having a higher boiling point than water, and forming the obtained cellulose nanofiber dispersion into a film by drying.SELECTED DRAWING: None
