Abstract Purpose. The article is devoted to the method of synthesis of flexible light and heat reflective metal layers on a polyethylene terephthalate substrate and the study of the obtained coatings.
Methods. Gravimetry, scanning electron microscopy, X-ray graphic analysis, X-ray structural analysis, electron probe X-ray microanalysis, atomic emission spectroscopy, atomic absorption spectrometry.
Findings. Combined Ni-P layers with a total thickness of up to 9–14 µm of a predominantly amorphous structure, containing up to 8–15 mol % of phosphorus (P) were obtained on polyester fabric. They have a coefficient of visible light reflection about 85%.
Application field of research. The metallized fabric with light and heat reflecting properties can be used in protective special clothes and technical products.
Conclusions. As a result of the research, the significant differences were found in the patterns of formation and functional properties of Ni-P autocatalytic coatings deposited on polyester materials with different types of surface film and fabric. Chemically metallized polyester fabrics and fibrous materials possess characteristics are of interest for the use in protective clothing and technical items.
Keywords electrically conductive metal layer, nanocomposite material, functional reflective coatings
