Study on the Fabrication and Characterization of Piezoelectric Paper Made With Cellulose
Abstract
This report deals piezoelectric paper made with cellulose by mechanically and electrically aligning regenerated cellulose films. Cellulose electro-active paper was prepared by dissolving cotton pulp in LiCl/N, N-dimethylacetamide solution and regenerating cellulose chains. An electric field was applied in the mechanical direction of cellulose films along with mechanical stretching. Alignment of cellulose chains was investigated in terms of applying electric field. The characteristics of cellulose films were analyzed by x-ray diffractometer, field emission scanning electron microscopy and high voltage electron microscopy. By applying the electric field, nanofibers of cellulose were generated and the crystallinity index was increased. When the piezoelectric charge constant was measured, it was gradually improved as increasing the applied electric field, which was associated with the increased cellulose crystallinity as well as the alignment of cellulose chains.
