Stretchable conductive electrodes are an essential component to transport electronic current without degradation, even under large deformation. To achieve reasonable electronic properties in soft electronics, it is necessary to transmit electronic signals through stretchable conductive materials to avoid loss of signal under strains. However, it is challenging to obtain stretchable electrodes with high stretchability (100%) and conductivity (>10<sup>6</sup> S/cm). Silver nanowire (AgNWs) is a great one-dimension candidate for a stretchable and conductive electrode due to their excellent electrical characteristics. The purpose of our research is to prepare a stretchable silver nanocomposite using AgNWs by modifying silver nanowires with polyisoprene via thiol-ene chemistry. The nanocomposite decreases the contact resistance to achieve high conductivity and low sheet resistance. Furthermore, Adding polyisoprene can effectively improve stretchability. The photo-cured stretchable electrodes show great solvent resistance under various organic solvents. The great solvent resistance makes the stretchable electrode patternable. Currently, our stretchable electrode patterning has been successfully developed to below 20 μm, and the sheet resistance can be controlled below 0.8 Ω sq<sup>-1</sup> under 100% strain. This work successfully demonstrates photo-patternable stretchable electrodes with low resistance and high stretchability.
