Introduction of CAS:PVDF-TRFE | Polyvinylidene fluoride copolymer P(VDF-TrFE)
P(VDF-co-TRFE) is a semi-crystalline thermoplastic at room temperature, and P(VDF-Co-TRFE) with a VDF mole fraction between 20 and 50% has a large PR. After high electric field or thermal polarization, its D31 and D33 can reach or even exceed 25 and -25 PC/N, respectively. The piezoelectricity is better than that of Β phase PVDF. Moreover, P(VDF-CO-TRFE) has a higher electromechanical coupling coefficient (KT) than traditional ferrovoltage-electric materials.

Research Application of CAS:PVDF-TRFE | Polyvinylidene fluoride copolymer P(VDF-TrFE)
P(VDF-CO-TRFE) piezoelectric material is a material that can convert kinetic energy into electrical energy after special processing, and can be used to make transducers, hydrophones, loudspeakers, microphones, pyroelectric sensors, pressure sensors, strain sensors, vibration control, acceleration sensors, energy harvesting systems, and new non-loss memory. It plays a unique role in the fields of defense, environment, agriculture, industrial monitoring and control, automatic building control, and property tracking. Compared with traditional monocrystals and ceramic piezoelectric materials, it has good plasticity and low elastic modulus, and can be made into various shapes, such as films, fibers and blocks, by simple preparation process.
