An experimental investigation was utilized to present the IR rejection performance of Cu-Ni-P-Ni composite double-layer electroless plated PET fabric compared to fabric samples composed of Cu-Ni-P metallic monolayer. Accordingly, the effect of a range of operational parameters was explored on the conductivity of electroless plated PET fabric. Results indicate higher conductivity and lower durability for Cu-Ni-P-coated samples compared to its counterpart with same sub-layer included with nickel on top layer. The SEM image of Cu-Ni-P particle on PET fabric shows a hexagonal non-homogenous morphology with nanoscale crack on its surface. However, the micrograph of the Cu-Ni-P-Ni electroless plated fabric shows an extremely compact and continuous phase with clear boundaries containing semispherical particles. The thermopile radiated sensing system was used as a sophisticated device to show the thermal energy absorption level. The acquired data indicate a 2.3 and 2.7 unit reduction in transmitted radiated power, respectively, for Cu-Ni-P and Cu-Ni-P-Ni conducting fabric. The captured thermal camera images of human body while keeping in front of a Cu-Ni-P conducting fabric revealed a nearly black and blue feature which proves the significant decrease in body radiated thermal energy. However, the thermal image of Cu-Ni-P-Ni conductive fabric shows almost black appearance in all areas. It can be presumably due to improving of the IR rejection performance and also formation of a massive barrier against body thermal radiation for promising camouflage applications.
