英文摘要：

Ferroelectric Poly （vinylidene fluoride）, PVDF, and its copolymers have attracted great interests due to a variety of interesting physical phenomena such as ferroelectricity, piezoelectricity, py- roelectricity, electric conductivity and photoelectricity, and have been widely applied in smart electronic devices because they are flexible, durable, corrosion resisting, easy shaped and simple fabricated. In this paper, we briefly summarized the basic physics of ferroelectricity in PVDF and its copolymers, and introduced recent research progresses in the field of wearable devices, fluidic devices and memory devices. Finally, some unsolved problems in these three fields are indicated and a few developing trends are prospected.
