Abstract
An advanced method of describing the impact of roughness on contact angles of different rough and varnished elastomers is presented here. The composition of coated elastomers was analysed by ATR-IR and SEM-EDX. The topography and coating thickness were examined by SEM and digital microscopy. Dynamic contact angles were estimated for solvents of different polarity by using the Wilhelmy method. The hysteresis of the contact angles was correlated with roughness parameters which were obtained by white light interferometry and measurements with the stylus instrument. From the contact angles, the polar and disperse parts of the surface energy were calculated by the OWRK method.
