Effect of IF-WS2 nanoparticles addition on physical-mechanical and rheological properties and on chemical resistance of polymeric coating and polyurethane paint
Abstract
In this paper a possibility of improving properties of protective coatings by adding nanoparticles of IF-WS2 is
examined. Nanoparticles were added to a standard polyurethane paint for military camouflage protection, in a
concentration of 1 wt.%, and dispersed in paint by ultrasonic irradiation. After the homogenization on the magnetic stirrer
the paints were applied to standard steel plates, and dried, for examinations of physical-mechanical properties and on
chemical resistance. The following physical-mechanical properties were compared for paint without and with IF-WS2
nanoparticles: hardness, flexibility, elasticity, abrasion resistance and stickness. Camouflage properties were also examined
- IR reflection and colorimetry. Also, resistances to salt water and agressive media were observed. The effect of adding IFWS2 on rheological properties of the two examined paints has been examined using Dynamic Mechanical Analysis (DMA),
observing viscosity as the function of the shear r...ate.
