Aqueous carbon nanoparticle ink composition for resistors

An aqueous ink composition comprising an aqueous solvent, one or more carbon nanoparticles, and one or more cellulose nanocrystals, wherein the aqueous solvent comprises water, wherein the one or more carbon nanoparticles comprises non-functionalized multi-walled nanotubes, and wherein the one or more cellulose nanocrystals comprises primary alcohol groups, and wherein the primary alcohol groups are oxidized to respective carboxylate groups, and wherein the one or more cellulose nanocrystals comprise a total acid content of from about 100 mmol/kg to about 1600 mmol/kg.

An aqueous ink composition comprising an aqueous solvent, non-functionalized multi-walled nanotubes, and one or more cellulose nanocrystals, wherein the aqueous ink composition has a viscosity at 25° C. of from about 1.22 cP to about 1.36 cP, wherein the multi-walled nanotubes are present in an amount greater than or equal to 33% of a maximum stable loading of the multi-walled nanotubes, wherein the one or more cellulose nanocrystals are carboxylated cellulose nanocrystals (CNC(COOH)) configured to facilitate the stabilization of the multi-walled nanotubes in the aqueous solvent, and wherein the carboxylated cellulose nanocrystals are present in an effective amount to stabilize the multi-walled nanotubes in the aqueous solvent.
