Abstract
$PbTiO_3$/P(VDF/TrFE) thin film for pyroelectric infrared sensor's sensing materials have been fabricated by spin coating technique. 65 wt% VDF and 35 wt% TrFE were for P(VDF/TrFE) powder. $PbTiO_3$ powder was used for a ceramic - polymer composites materials. Surface of composite thin film by ceramic fraction factor was observed by SEM. The $PbTiO_3$/P(VDF/TrFE) thin film capacitancy, dielectric constant and dielectric loss measured by impedence analyzer(HP4192A) and pyroelectric coefficient was measured by semiconductor parameter analyzer(HP4145B).
