Abstract:
In a method of manufacturing a highly stretchable three-dimensional (3D) percolated conductive nano-network structure, a 3D nano-structured porous elastomer including patterns distributed in a periodic network is formed. A surface of the 3D nano-structured porous elastomer is changed to a hydrophilic state. A polymeric material is conformally adhered on the surface of the 3D nano-structured porous elastomer. The surface of the 3D nano-structured porous elastomer is wet by infiltrating a conductive solution in which a conductive material is dispersed. A 3D percolated conductive nano-network coupled with the 3D nano-structured porous elastomer is formed by evaporating a solvent of the conductive solution and removing the polymeric material.
