Electrogenetic tissues are soft and stretchable materials. However, most of the artificial materials have stiff mechanical properties. The contradictory properties between those cause critical incompatibility problems in implanting body machine interfaces. Thus, we developed a stretchable and electrically conductive material. an implantable polycaprolactone(PCL) membrane was coated by layer-by-layer(LBL) assmebly of single-walled carbon nanotubes(SWNTs) or poly(3,4-ethylenedioxythiophene)(PEDOT). The soft PCL membrane with asymmetric pores provides elastic properties, while conductive SWNT or PEDOT coating preserves stable electrical conductivity even in a fully stretched state. This electrical conductivity enhanced ionic cell transmission and cell-to-cell interactions. Our novel stretchable conducting materials will reduce mechanical property gaps between tissues and artificial materials and provide electro-active pathways which can be available even at a fully stretched state. |
