Performance Evaluation of Electro-Active Paper Based on Aligned Cellulose

배향된 셀룰로오스에 기초한 Electro-Active Paper의 성능평가

This study focused on investigating the effect of aligned cellulose fibers to the performance of EAPap actuator. The performance of EAPap is dependant on the material direction of cellulose film. Electrospinning was used to improve material directionality of EAPap. DMAc cellulose solution which cotton pulp was resolved in DMAc solvent was used for electrospinning cellulose film. To increase directionality of nano fibers, the Electrospun film was stretched by 10 % strain during drying process. Induced in-plane strain of Electrospun EAPap was proportional to the applied voltage and larger than that of spincast EAPap. It is concluded that the performance of EAPap was improved by aligning cellulose fibers.
