Polymer film made with PVDF homopolymer, PVDF-HFP, PVDF-CTFE, PTFE-HFP-VDF, PVDF-TrFE-CTFE, PVDF-TrFE-CFE. They have high dielectric constant from 10 to >50 (pure polymer without any fillers) and high dielectric breakdown strength (500-800 MV/m). They can be used in high energy density film capacitors, actuators, and other applications. They can also be used in soft robotics.
Most of the film are uniaxially or biaxially oriented with high dielectric breakdown strength and uniform thickness. They are sold either in 200 mm x 250 mm paper size for R&D or in small rolls >100 m.
The PVDF film can be either in alpha phase or in beta phase (no poling).
Ultrathin Film with high dielectric constant: Energy Storage Capacitors, Piezo Sensors, Transducers, Soft Actuators, Electrocaloric Cooling, Hydrophone, etc.
