▎ 摘　　要

A patterned electrode film with ultrahigh conductive stability and transparency is obtained via inkjet printing based on a kind of high-stability conductive ink and a viscoelastic state substrate. The Ag@Au nanotriangle platelets and graphene oxide hybrid (Ag@Au NTPs-GO) nanomaterial ink was synthesized. Then, it is inkjet-printed on the specific viscoelastic state base to improve the accuracy of patterns, and a flexible and transparent conductive film with Ag@Au nanotriangle platelets and reduced graphene oxide hybrid (Ag@Au NTPs-rGO) patterns was obtained after reduction. The patterns show no undesirable coffee ring effects, and the inkjet-printed rGO-based lines with B7 mm width and a film with high transparency (similar to 98%) are achieved. Meanwhile, the structure models of Ag-rGO and Ag@Au-rGO are built and calculated. It is found that the addition of a thin layer of Au coated on the surface of Ag can effectively reduce the surface energy of the Ag-reduced graphene oxide material and improve the stability of the material's conductivity. These enhancements of the printed film benefit from the core@shell structured nanomaterial, the viscoelastic state substrate and the high resolution patterns. This facile strategy will be significant for highly stable integrated circuit boards and highly transparent devices.
