Abstract

In order to examine the possibility to improve its camouflage properties standard cotton fabric with camouflage print was impregnated with poly(vinyl butyral), PVB and fullerene-like nanoparticles of tungsten disulfide, PVB/IF-WS<subscript>2</subscript>. FTIR analysis excluded any possible chemical interaction of IF-WS<subscript>2</subscript> with PVB and the fabric. The camouflage behavior of the impregnated fabric has been examined firstly in the VIS part of the spectrum. Diffuse reflection, specular gloss and color coordinates were measured for three different shades (black, brown and dark green). Thermal imaging was applied to examine the camouflage abilities of this impregnation in IR part of the spectrum. The obtained results show that PVB/IF-WS<subscript>2</subscript> impregnation system induced enhacement of the materials camouflage properties, i.e. that IF-WS<subscript>2</subscript> have a positive effect on spectrophotometric characteristics of the fabric.
