Conductive tissues in body consist of soft and flexible materials, but most artificial materials have rigid mechanical properties. For electrically conducting soft biomaterials, we developed an electroconductive material providing soft and stretchable with hierarchical structures. The membranes have hierarchically structured 3D network of conductive paths, providing softness as well as stretchable, anisotropic electrical conductivity. For applications in bioengineered devices, an implantable polycaprolactone (PCL) membrane was coated on single-walled carbon nanotubes (SWNTs) via layer-by-layer (LBL) assembly for electroconductivity. This electrical conductivity enhanced ionic cell transmission, electrical cell stimulation, and cell-to-cell interaction. |
