Properties of polymers
Electrical properties
Mechanical properties
Physical properties
Chemical properties
The work in the area of piezoelectric polymers has led to the development of strong piezoelectric activity in polyvinylidene fluoride (PVDF) and its copolymers with trifluoroethylene ( TrFE) and tetrafluoroethylene (TFE).
These semicrystalline fluoropolymers represent the state of art in piezoelectric polymers.
Applications and Future Considerations
The application potential for piezoelectric and other electroactive polymers is immense. To date, ferroelectric polymers have been incorporated into numerous sensing and actuation devices for a wide array of applications. Typical applications include devices in medical instrumentation, robotics, optics, computers, ultrasonic, and electroacoustic transducers.
One important emerging application area for electroactive polymers is in the biomedical field where polymers are being explored as potential artificial muscle actuators, as invasive medical robots for diagnostics and microsurgery, and as sensors to monitor vascular grafts and to prevent blockages. Such applications are ideal for polymers since they can be made to be biocompatible and they have excellent conformability and impedance matching to body fluids and human tissue.
