Dry Electroactive Paper Actuator Based on Cellulose/Poly(Ethylene Oxide)

Abstract

Cellulose Electroactive Paper (EAPap) is an attractive material to construct biomimetic actuators and MEMS devices due to its lightweight, biodegradability, large displacement, and low actuation voltage. However, the performance of the actuator is sensitive to humidity levels. In this article, cellulose/poly(ethylene oxide) (PEO)—poly(ethylene glycol) (PEG) microcomposites were fabricated for EAPap actuators working at ambient humidity condition, and the effect of different PEO : PEG ratios (0.95 : 0.05 to 0.99 : 0.01) on the actuation behavior was investigated. Based on the bending displacement, power consumption, and durability, 0.95 :0.05 ratio was identified as an optimum ratio of PEO : PEG to blend with cellulose for EAPap actuator. The actuation mechanism of the cellulose/PEO—PEG actuator was addressed.
