Abstract :
0-3 PbTiO/P(VDF/TrFE) nanocomposites thin films for pyroelectric infrared sensor have been fabricated by composites suspension technique. 65 wt% VDF and 35 wt% TrFE was formed to a P(VDF/TrFE) powder. Nanometer size particle PbTiO3 powder was used. 0-3 connectivity of PbTiO3/P(VDF/TrFE) composites film is achieved and also observed by SEM photography. The dielectric constant, and pyroelectric coefficient measured and compared with P(VDF/TrFE) copolymer. A very low dielectric constant (13.48 at 1 kHz) and high enough pyroelectric coefficient (3.101 nC/cm2middotk at 50 degC) measured. This nanocomposites thin film can be used for a new pyroelectric infrared sensor for better performance
