▎ 摘　　要

NOVELTY - Preparing (100) a graphene-based conductive film comprises: adding (104) conductive polymer into graphene-based nanoparticles colloid to obtain a functionalized colloid; adding (110) dispersants into the functionalized colloid; vortexing (112) the functionalized colloid to obtain a graphene-based conductive polymer dispersion liquid; and depositing (116) the graphene-based conductive polymer dispersion liquid on a substrate to form the graphene-based conductive film. USE - The method is useful for preparing graphene-based conductive film which is a reduced graphene oxide-silver nanoparticles conductive film (all claimed) for flexible electronics that is used in rollable displays, electronic paper, flexible cellular phone, solar cells, radio-frequency identification-tags, wearable sensors for health monitoring, lab-on-a-chip for disease diagnostics, and flexible temperature sensors for healthcare. ADVANTAGE - The method is simple, cost-effective and harmless for preparing graphene-based conductive film by eliminating the use of toxic chemicals, which has improved hardness without degrading its electrical performance and shows better electrical performance e.g. resistance, resistivity and conductivity.
