Abstract

Stretchable semiconductors are indispensable to producing wear-able electronics, but highly stretchable organic semiconductors generally exhibit low electrical characteristics and weak mechanical properties during stretching, cracking thin-films. In this study, conjugated organic semiconductors with high electrical properties fabricate by blending with a certain amount of polystyrene-block-poly(ethylene-ran-butylene)-block-polystyrene (SEBS). These organic semiconductors composites that composed of DPP-DTT and SEBS showed high stretchability and robustness for mechanical deformation as well as to align the semiconductor in the vertical direction. With this approach, we are enabled to manufacture high-performance stretchable organic transistors for applications of stretchable displays and wearable devices.
