N2 - The Development of various flexible and stretchable materials has drawn interest for promising applications in the biomedical field, such as health care monitoring, artificial intelligence, wearable electronic skins. However, it's still challenging to achieve tunable sensitivity and stretchable property based on a particular application from large strain to minor strain. Herein, we present interconnected nanocomposite PANI-CNT impregnated in polyurethane polymer. Filler materials PANI are prepared by chemical oxidation method, and CNTs are surface modified by acid oxidation method. Nanocomposite was prepared by the solvent-casting method using polyurethane polymer. The subsequent change of electrical behavior was observed when the concentration of PANI increased in the nanocomposite. These prepared nanocomposites exhibited electrical conductivity and stretchability. Furthermore, nanocomposites are attached to the elbow and observe the change in bending movements of elbow. Altogether, prepared PANI-CNT/PU nanocomposite can be assembled as e-skins for various purposes such as healthcare, human motion monitoring and human-machine interface.
