Title: Fully embedded CuNWs/PDMS conductor with high oxidation resistance and high conductivity for stretchable electronics

Abstract

Currently, copper nanowires (CuNWs) based conductors have been considered as a promising candidate in the area of stretchable electronics. But the fast degradation of CuNWs in ambient conditions largely limited their practical applications. Here, the author reports a highly conductive, stable, and stretchable conductor with CuNWs fully embedded in the surface layer of poly(dimethylsiloxane) (PDMS), which not only exhibit superb stability against oxidation, but also possess good conductivity. In the fully embedded conductor, PDMS protects the CuNWs from oxidation and increases the mechanical robustness of CuNWs networks at the same time. The stretchable conductor could maintain a low sheet resistance even after 1000 cycles of stretching under 30% of strain. In addition, fully embedded CuNWs/PDMS conductors have excellent oxidation stability even in high humidity and high temperature environments (85 °C, 85 % RH). Stretchable dipole antenna was fabricated using the fully embeded CuNWs/PDMS conductors, which could retain its sensitivity to specific radio frequencies even after 500 cycles of the stretching/releasing process. At the same time, a stretchable conductive heater was demonstrated, verifying the applicability of our fully embedded conductor. We believe that this work could opens new opportunities for CuNW-based conductor into broad practical applications.
