Resistance change of stretchable composites based on inkjet-printed silver nanowires

The stretched resistance fluctuates of composites based on inkjet printed silver nanowire (AgNW) and polydimethylsiloxane (PDMS) are controlled by different ratio of curing agent in PDMS, with an optimized normalized resistance change as low as 4.67% in 50% tensile testing cycle. The results confirms that the properties of PDMS including Young's modulus and creep deformation play key roles in controlling the resistance changes of stretched AgNW-PDMS composites based on inkjet printed AgNW, which opens up the applications of inkjet printable elastic AgNW conductors in stretchable electronics.
