Conductive ink can be widely applied in printed electronics to print high conductivity and flexible electrodes, especially for large-area formats with low cost considerations. In this article, we demonstrated that the in situ prepared silver nanoparticles decorated graphene conductive ink was suitable for flexible electronics. By using liquid phase exfolication method and reducing the silver salt to nano silver at the same system which addressed the heterogeneous issue of silver decorated graphene. The inkjet-printed graphene features attained low resistivity of 20 +/- 1 Omega/rectangle after a thermal anneal at 400 degrees C for 30 min while showed uniform morphology, compatibility with flexible substrates.
