0-3PbTiO3/P (VDF/TrFE) nanocomposites thin films for passive pyroelectric infrared sensor have been fabricated by two-step spin coating technique. 65 wt% VDF and 35 wt% TrFE was formed to a P(VDF/TrFE) powder Nano size pbTiO3 powder was used. 0-3 connectivity of PbTiO3/P(VDF/TrFE) composites film is achieved and also observed by SEM photography successfully. The dielectric constant, and pyroelectric coefficient measured and compared with P (VDF/TrFE). A very low dielectric constant (13.48 at 1 kHz) and high enough pyroelectric coefficient (3.101 nC/cm2·k at 50oC) neasured. This nanocomposites can be used for a new pyroelectric infrared sensor for better performance.
