Stretching method with different wet-drawing ratios was introduced to increase the piezoelectric property of cellulose paper during regeneration process.It is observed that the Young's modulus and the piezoelectric charge constants are very dependent on the drawing ratio and the direction of nanofibrils of piezoelectric paper.Using the enhanced piezoelectric property,we prove that the flexible regenerated piezoelectric cellulose can be applied to the potential acoustic applications such as thin piezoelectric paper speaker.展开更多

文摘We report the fabrication process of piezoelectric cellulose paper and the enhancement method of its piezoelectric property.
