Abstract
As interest in stretchable and wearable devices increases, research on stretchable electrodes is being actively conducted. A metal mesh that maintains electrical and optical properties despite mechanical deformation is one of the most attractive transparent electrodes. In this study, a transparent electrode with a very smooth surface was formed by embedding a silver mesh in polydimethylsiloxane, a stretchable substrate. In addition, through the laminated structure with the conductive polymer Poly(3,4-ethylenedioxythiophene), it was possible to obtain current homogeneity and maintain the conductivity of the electrode over 80% at high tensile modulus (∼30%). The fabricated bilayer electrode showed a transmittance of over 80% at a wavelength of 550 nm, and the root mean square roughness was maintained at less than 3 nm even after more than 500 stretching tests.
