Abstract
Piezoelectric films including ionic liquids and methods of making piezoelectric films including ionic liquids. The resulting films have higher levels of beta phase and can be poled using external fields without additional treatment, such as stretching. The films are light-transparent. In some embodiments, the piezoelectric material is used to create piezo-electrophoretic films that can be patterned for use as security markers, authentication films, or sensors. The films are generally flexible. Some films are less than 100 μm in thickness. Electrophoretic displays formed from the piezoelectric films do not require an external power source.
