Title: Ferroelectric Polymer for Thermodielectric Energy Conversion
Abstract: There have been few reports on the application of ferroelectric materials for direct thermal to electrical energy conversion. The basic principle utilizes the conversion of heat energy directly into electrical energy with or without utilizing the high dielectric constant anomalous peak values around the transition temperature of ferroelectrics. Thin-film form of the material and polymers are supposed to give suitably superior conversion efficiency. The choice of material as sheets of ferroelectric polymer polyvinyledene (PVF 2 ) has been characterised. General analysis indicates better conversion efficiency with respect to other ferroelectric films or polymer sheets with maximum limit of power output. The energy ratio i.e. the ratio of the input heat energy to the obtainable electrical energy is assessed to be around 0.861.
