This study reports on the fabrication and performance evaluation of camouflage coatings based on Cr2O3 nanoparticles and polyurethane resin. Cr2O3 nanoparticles were synthesized via a combustion method using Cr(NO3)3·9H2O as the precursor and glycine as a fuel at a glycine/NO3 ratio of 9:1. The obtained Cr2O3 nanoparticles, with sizes ranging from 40 to 60 nm, were uniformly dispersed within the polyurethane (PU) matrix coated onto the polyester fabric surface. Thermal imaging analysis using a FLIR BHM-Series Bi-Ocular Thermal Imaging Camera confirmed that the coatings provided enhanced and prolonged camouflage effectiveness.
