Development of elastomer electrodes with bulk metal-like conductivity and elastomer-like mechanical properties has been strongly demanded for next-generation flexible electronics. Here, we introduce a solvent swelling- and nanoparticle assembly-induced wrinkled elastomer with highly stable metallic conductivity. The layer-by-layer assembly of metal nanoparticles and small organic linkers onto elastomer generated highly wrinkled surface morphology and remarkable electrical conductivity (1.7 x 105 and 1.1 x 104 S cm−1 at 0 and 100% strain, respectively). Particularly, the formed elastomers exhibited high electrical conductivity of 2.8 x 104 S cm−1 even after repetitive peeling tests of 1000 cycles. Furthermore, when the wrinkled elastomer was applied to the triboelectric nanogenerator (TENG), it exhibited the output voltage and current density of 198 V and 17.2A cm-2, outperforming the performance (50 V and 2.8 A cm-2) of TENG with rigid and flat metal electrode. |
