Graphene-based conductive ink of different proportions was analyzed with the research on its application. The conductive inks with mass fraction of added graphene of 26 %, 28 %, 30 % and 32 % were labeled as sample A, B, C, and D respectively. The electrical resistivity and ink fineness of four groups of samples were measured in order to analyze the printing quality. The result indicated that: firstly, the resistivity of the conductive ink gradually decreased with the increasing amount of graphene, while sample D reached the lowest of 5.42 Ω cm. Secondly，the ink fineness increased gradually with the increasing amount of graphene in the range of the ink fineness of silk-screen printing. Thirdly, the conductive ink of the sample D performed the best in printing quality. The optimal ratio of conductive inks could be with 18% of linking acrylic resin, 34% of ethanol, 11% of glycerol, 2% of benzoate, 2% of conductive toner, 1% of PE-wax, 32% of conductive material graphene. Sample D conductive ink with good electrical conductivity realized high printing quality.
