▎ 摘　　要

NOVELTY - Conductive ink comprises graphene sheets, where about 90% of the graphene sheets consist single layer, the graphene sheets have an oxygen content of about 6%, a binder, a stabilizer, and a solvent. USE - Conductive ink used in such devices as touchscreens, solar cells, sensors, flexible displays, foldable displays, electronic paper, sensors, radio-frequency identification (RFID) tags, batteries, and supercapacitors. ADVANTAGE - The conductive ink improves elasticity, adhesion, flexibility, strength, thermal stability, coating uniformity, chemical stability, and tunable viscosity, conductivity and ink's ability for uniform coating on a substrate while preventing cracking and island formation.
