Interfacial and electrical durability of CNT or ITO/PVDF nanocomposites were investigated for sensor and actuator applications. CNT and ITO/PVDF nanocomposites exhibited lower electrical resistivity due to inherent property, and showed good sensing performance. Durability on the interfacial adhesion was good for both CNT and ITO nanocomposites. With contact angle measurement, surface energy, work of adhesion between either CNT or ITO and PVDF were obtained to verify the correlation with the durability of interface. The optimum actuation performance of CNT or ITO/PVDF specimen was measured by the displacement using laser sensor. Due to nanostructure and inherent electrical properties, CNT/PVDF nanocomposite exhibited better performance as sensor and actuator than ITO/PVDF case.
