Smart materials, also known as stimuli responsive materials, 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 deformation in response to electrical or thermal stimuli. The long-term objective of this program is to develop a hierarchical manufacturing platform  for smart materials with tailored multi-functional behaviors (i.e., electro-mechanical, thermo-mechanical, and electro-thermal). The proposed research aims to bridge the gap between the structure of electrically conductive polymers ECPs and 1D and 2D nanoparticles and their manufacturing methodologies. Designing and tailoring the properties of EAP sensory and TAP actuation elements requires a bottom-up approach from self-assembly to a macroscopic hierarchical dual sensor/actuator system through which this smart materials manufacturing platform will be developed. A major application of EAPs/TAPs hybrid is in electronic skins (e-skins), which are flexible, stretchable, and conformable substrates with sensing/actuation capabilities.
