Vinylidene fluoride (VDF)-based fluoropolymers have been widely used in electrical application areas, including electric energy storage and harvesting, electromechanical sensors, electrostrictive actuators, etc, because it shows favorable dielectric, ferroelectric, piezoelectric properties. To use them into various applicable fields, VDF has been copolymerized with chlorotrifluoroethylene (CTFE), hexafluoropropylene (HFP), trifluoroethylene (TrFE). However, insufficient information about the effects of co-monomers on properties of copolymers make it difficult to utilize it. In order to improve this restrictive things, we investigated the change of crystalline properties according to inclusion of CTFE unit in PVDF film. |
