PYROELECTRIC RESPONSE OF FERROELECTRIC PVDF AND THEIR COPOLYMER: A REVIEW

The world's conventional energy sources are fast depleting due to population growth and civilization expansion. Subclasses of piezoelectric materials include ferroelectric and pyroelectric materials. Materials with permanent polarization as a result of their chemical composition are called ferroelectric materials. However, the spontaneous polarization that happens in pyroelectric materials when they are exposed to temperature changes. With the use of ferroelectric, pyroelectric, and piezoelectric materials, waste environmental energy is mainly transformed into electrical energy. Modern electronics are designed with reduced power consumption in consideration. Materials based on polymers are thought to be viable options for these devices. Because of its low thermal conductivity and permittivity, flexibility, processability, greater output performances, and affordability, PVDF and its family of polymers(copolymer & terpolymer )are widely employed in device applications.
