Based on a deformable elastomer electrolyte of ionic thermoplastic polyurethane (i-TPU), highly stretchable, high-mobility, and free-standing all-organic transistors exhibited high mechanical reliability with low-voltage operation. The i-TPU electrolyte has outstanding features, i.e., a large specific capacitance, high transparency, flexibility, and even stretchability. Not only bendability and stretchability, these i-TPU based organic transistors also showed a hole mobility as high as 7.9 cm2V-1s-1 and operated in a low-voltage operation. In addition, carrier mobility, on-current, and threshold voltage are maintained even under the concave and convex bending state. Lastly, fully stretchable and semi-transparent coplanar-type all-organic transistors can be fabricated with a PEDOT:PSS layer as source/drain and gate electrodes, performing low-voltage operation and an even higher mobility of up to 17.8 cm2V-1s-1. Moreover, these devices withstand stretching up to 80% tensile strain. |
