We summarized a few of the results reported in the literature, as shown in Table S1 . In order to further discover the impact of the microstructures on the electrical properties of the printed pattern, we fabricated the printed patterns with totally different printed layers. Figure 5 shows the sheet resistance of the printed patterns fabricated with the printed layers from 1 to 7. When the number of printing layers was lower than three, the printed pattern was non-conductive. The cause behind this is that there were too few silver nanoparticles formed in situ to attach with one another to kind an efficient conductive path. In growing of the variety of printing layers, the sheet resistance of the printed sample progressively decreased. The electrical conductivity of the printed sample was achieved by contact between the silver nanoparticles shaped in situ.
