Enhancement of Capacitance in Piezoelectric Sensors Based on PVDF-TrFE by Photothermal Effect of Conjugated Polymer Nano-particles |
| 초록 |
Ferroelectric polymers have been widely studied for piezoelectric applications because of their advantages including facile shaping process and surfaces at low cost. In this study, we present the influence of self-heating on the properties of piezoelectric sensors, using representative ferroelectric polymer poly(vinylidene fluoride-trifluoroethylene) (PVDF-TrFE). As capacitance is proportional to the permittivity, and in the case of PVDF-TrFE, the dielectric constant is proportional to temperature below 120 Celsius degrees. Due to facile orientation of dipoles, one can expect a significant increase in capacitance of devices. We prepared conjugated polymer nano-particles (CPNs) that efficiently harvest sunlight energy and release the energy as heat, and fabricated capacitors based on the composite films of PVDF-TrFE and CPNs. We characterize the structural variation and morphology of the films and investigate how the photothermal CPNs influences on capacitance under light irradiation. |
