Synthesis, property and application of PZT/P(VDF-TrFE) composite film fabricated on polyimide substrate

Abstract

In this paper, a flexible pyroelectric sensor using PbZr 0?3 Ti 0?7 O 3 PZT/P(VDF-TrFE) materials on the polyimide (PI) flexible printed circuit substrate was reported. The fabrication processes, material electric properties and infrared photoelectric response property of the designed sensor were studied. First, the PZT ceramic powder was annealed at temperatures ranging from 300 to 900uC, and then 0-3 PZT/PVDF-TrFE composites films were produced by casting PZT/PVDF-TrFE suspension onto the flexible PI substrates. The highest pyroelectric coefficient obtained using 700uC annealed PZT particulates was 96 mC m 22 K 21 , which was 20% higher than that of unannealed powders. The PI thermal insulation layer and thermal insulation tanks fabricated by laser microetching have been used to improve the photoelectric response ability of the infrared sensor. The specific detectivity of the sensors was calculated from the voltage responsivity and noise. Detectivity D* of the PZT/P(VDF-TrFE) infrared sensor was 1?17610 8 cm Hz 1/2 W 21 at 138?3 Hz modulation frequency. These results demonstrate that the pyroelectric infrared sensor possesses potential applications in flexible electronics.

Polymer‐/Ceramic‐based Dielectric Composites for Energy Storage and Conversion

“…By taking full advantage of the inorganic ceramic filler and the organic polymeric matrix, ceramic-polymer composites are candidates for self-powered sensor applications. As a result, all types of ceramic-polymer composite-based sensors have been under exploration with great attraction, including PZT, BT nanofibers, and nanoparticles in combination with PVDF, [154,155] PVDF-TrFE, [156,157] polydimethylsiloxane (PDMS) nanowires, [158] and so on. Such ceramic-polymer composites exhibit good mechanical flexibility and structure reversibility.…”
