      The aim of this research is the fabrication of infrared detector for using in different fields. For this purpose, polyaniline/silver nanowire nanocomposite was synthesized by hard chemical template method. The structural characteristics of the prepared nanocomposite were examined by a scanning electron microscope (SEM) and X-ray diffraction (EDS) spectroscopy. The results of the microscopic analysis showed that the synthetic polyaniline film had a non-uniform porosities with the approximate size distribution in diameter of 270 nm and had contain 1.28 (wt.%) of silver nanowires in the size of 80-100 nm. The results of evaluating the performance of an infrared detector based on the polyaniline/silver nanowire nanocomposite showed that with infrared light, the detector current increases under constant orientation (bias) and returns to its original state when the radiation is stopped. This increase was 4.8%, which indicates an improvement in comparison with prior similar samples. The response and the recovery time were obtained about 30 and 8 s, respectively.
