Stretchable electronics, which require the stretchability necessary to endure complex motions from humans, have recently attracted considerable attention for bio-implantable and wearable devices. In this talk, we suggest several self-assembly based approaches for structure-assisted stretchable transparent/energy storage electrodes. We firstly introduced an ideal stretchable Ag NW network nanostructure consisting of in-plain wavy Ag NW strands with large radius of curvature by a floating-compression process like Langmuir-Blodgett self-assembly. The second part, we introduce novel 2D reentrant cellular structures of porous graphene/CNT networks for omnidirectionally stretchable supercapacitor electrodes. The 2D reentrant structures of graphene/CNT networks maintained excellent electrical conductivities under biaxial stretching conditions and showed a slightly negative or near-zero Poisson’s ratio over a wide strain range because of their structural uniqueness. |
