Stimuli responsive polymers are drawing significant research attention due to their improved reliability, performance, flexibility and miniaturization compared to their traditional counterparts. Electroactive polymers (EAPs) and thermoactive polymers (TAPs) are classes of smart materials that undergo change in response to electrical and thermal stimuli, respectively. Actuators have been widely used in industrial, electronics and biomedical applications. These actuators can provide superior power and speed in comparison to biological muscles. However, complexity and bulkiness are two of the major weaknesses that prevent electronic-based actuators from being implemented in biomimicking and biomedical applications. Recent advances in material sciences have suggested the possibility of flexible material-based actuators. These “smart material” actuators can be constructed by combining different composite materials, and motion or deformation can be observed once the actuator is subjected to a proper stimulus. This paper presents the development of novel active hybrid composites. Starting with a well-known polymeric blend shape memory polymer (SMP) and electrothermal actuator (ETA) system, the composites were first modified with nanoparticles to achieve room temperature deformability. The plasticizing effect was then utilized to enhance the actuation temperature, while conductive filler was implemented to enable electroactive ability.
