Paper Abstract

Material properties of Electro-active paper (EAPap) actuator were investigated under different environmental conditions such as humidity and temperature. Understanding of humidity and temperature effects on the material behavior of EAPap during visco-elastic deformation regime provided useful information on structural changes of EAPap by environmental factors. The pulling test results showed that the humidity and temperature heavily impact the mechanical properties of EAPap. Electro-mechanical coupling effects were investigated by applying electric field during the pulling test. Change of elastic modulus under different electric fields provides directional dependency of EAPap and strong shear electro-mechanical coupling. Creep behavior of cellulose paper was studied to figure out mechanical strength of EAPap under different ambient conditions. Tests under different humidity levels with fixed temperature and different temperatures with fixed humidity provided the coupled hygrothermal effects on the performance of EAPap.
