▎ 摘　　要

NOVELTY - An electroconductive composition comprises cellulose nanofibers (A), inorganic powder chosen from graphene, graphene oxide and their derivatives, and microparticles. USE - Electroconductive composition is used as coating material and ink for forming antistatic film, sheet and base material. ADVANTAGE - An electroconductive composition has improved electroconductivity by using cellulose nanofibers and inorganic powder having electroconductivity at nanoscale size. The electroconductive composition has excellent anisotropic conductivity and transparency. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for manufacture of electroconductive composition, which involves forming dispersion liquid by adding water or water/hydrophilic solvent dispersion liquid to cellulose nanofibers (A) and inorganic powder (B), and removing water or water/hydrophilic solvent from the dispersion liquid.
