High-performance, biaxially stretchable conductor based on Ag composites and hierarchical auxetic structure

A hierarchical-patterned stretchable conductor with multidirectional stretchability and stable conductivity under high stretching is fabricated by incorporating silver (Ag) flakes into a poly(dimethylsiloxane) (PDMS) matrix. Highly conductive composite films with an optimal structure exhibit both superior conductivity (7600 S cm−1) and stable electrical resistance (ΔR/R0 < 0.2) up to 50% biaxial strain.
