| Summary: | Transparent conductors for the next generation of soft electronic devices need to be highly stretchable, conductive, and transparent, while an inevitable challenge lies in enhancing them simultaneously. Cost-effective silver nanowires (AgNWs) are widely used but the conventional random network yields a high junction resistance as well as degraded conductivity in the stretched state. Here, a novel, facile, and versatile agitation-assisted assembly approach is reported to control the orientation direction and density of AgNWs and to layer-by-layer deposit the AgNWs monolayer or multilayers onto the prestrained soft substrate. This electrode demonstrates an unprecedented low sheet resistance of 2.8 Ω sq−1 as well as high transparency of 85% and high stretchability of 40%. It is interesting to note that contrary to most other reports, such a device shows higher conductivity in the stretched state compared to the released state. |
