It is the making of piezoelectric paper base on mechanically and electrically aligning regenerated cellulose films.
By dissolving cotton pulp in LiCl/N, N-dimethylacetamide solution and regenerating cellulose chains will be gain cellulose electro-active paper
The mechanical direction of cellulose films apply an electric field along with mechanical stretching.
Using X-Ray diffractometer can analize the characteristics of cellulose films, and electron microscopy and high voltage electron microscopy can be scanned by field emission.
Nanofibers of cellulose were generated and the crystallinity index was increased by applying the electric field.
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.
