Printable and Highly Stretchable Viscoelastic Conductors with Kinematically Reconstructed Conductive Pathways

. The stretch-induced kinematic movements of Ag flakes inside the polymer matrix, together with the reorganization and stabilization mechanisms, are unraveled and validated by the dissipative particle dynamics simulations. This unique phenomenon enables high-performance stretchable conductors to be fabricated with significantly reduced conductive fillers. The printable and stretchable composites presented here hold great promise for use in soft and stretchable electronics, as demonstrated in stretchable light-emitting diode arrays and wearable electronics.
