Paper Abstract

Piezoelectricity is one of major actuating mechanisms of a cellulose-based Electro-Active paper (EAPap). Wet drawn stretching method was introduced in the fabrication process of cellulose film to increase piezoelectricity of EAPap. The characteristics of wet drawn cellulose were studied by scanning electron microscope (SEM), X-ray diffractogram (XRD) and pull test. The performance of EAPap was evaluated by measuring bending displacement and piezoelectric charge constant. The performance of EAPap was sensitive to the fabrication process and material orientation of cellulose film. Aligning cellulose fibers in the fabrication process was a critical parameter to improve mechanical and electromechanical properties of EAPap. The experimental results provided that wet drawn stretching is an effective fabrication method to improve mechanical stiffness and piezoelectricity of EAPap.
