As a novel piezoelectric material, the mechanical and piezoelectric properties of cellulose electro-active paper (EAPap) were studied. Young’s modulus of piezoelectric EAPap was dependant on the material orientation as compared with other EAP materials. The highest Young’s modulus was obtained at 0° direction, while the highest direct piezoelectric charge constant was achieved at 45°. By measuring...
The effect of heat treatment on the structure, piezoelectricity and actuation behavior of cellulose electroactive-paper actuators was studied by infrared spectroscopy, piezoelectricity measurement and the tip displacement test. After heat treatment at 60°C for 2h, the piezoelectric coefficient (d 31 ) was enhanced nearly 10-fold as compared to that of non-heat-treated films. However, when...
