Abstract
Cellulose-based electro-active paper (EAPap) has been reported as a smart material that hasmerits in terms of light weight, dry condition, biodegradability, large displacement outputand low actuation voltage. However, it requires high humidity. This paper introduces anEAPap that can be actuated in low humidity conditions. The fabrication process andperformance test of the EAPap actuator are illustrated. Cellulose fibers were dissolved inN,N-dimethylacetamide/lithium chloride. The solution was cast and immersed in water to formthe cellulose film, followed by adding glycerol and lithium chloride aqueous solution, anddrying in air. Depositing thin gold electrodes on both sides of the cellulose film made abending EAPap actuator. Effects and optimum values of the glycerol content and thethickness of the films are discussed.
