Effect of the Surface Roughness on the Surface Free Energy of Coated Papers

Popis výsledku v původním jazyce

The surface properties of two sets of coated printing papers were studied by monitoring the dynamic behaviour of a small drop of a standard liquid (water, ethylene glycol, formamide and methylene iodide) in the time region of 20 s after the impact of thedrop on the solid surface (the "sessile" drop method). The contact angle, formed by the liquid drop at the three-phase boundary, is a quantitative measure of the wetting of a solid by a liquid. The usual aim of contact angle measurement is the calculation of the surface free energy (SFE) of the solid, using semi-empirical equations including the estimation of interfacial interaction between the liquid and the solid phases. Using the "cos theta model", published in (1-4), the pseudo-equilibrium contactangle, the liquid spreading rate k1 and the rate of liquid penetration k2 were evaluated. The surface roughness was measured by a profilometer and by the Parker Print-SurfTM instrument. The roughness values obtained by both methods correl
