Abstract

See full text

A conducting composition of the present invention includes a cellulose nanofiber and a fine particle. The conducting composition includes (A) a cellulose nanofiber, and (B) at least one type of an inorganic powder selected from graphene, graphene oxide, and derivatives thereof. A method for producing the conducting composition includes preparing a dispersion by adding water or a mixed solvent of water and a hydrophilic solvent to (A) a cellulose nanofiber and (B) at least one type of an inorganic powder selected from graphene, graphene oxide, and derivatives thereof, and removing the water or the mixed solvent of water and a hydrophilic solvent from the dispersion. Accordingly, the present invention provides a conducting composition that utilizes a cellulose nanofiber and an inorganic powder having the conductivity at a nano-scale size, can improve the conductivity, and further can have properties such as anisotropy and transparency.
