“…5 and 6. It is in contrast to the suggestions of Neumann et al (1974) and in accordance to the other investigators (Jańczuk and Białopiotrowicz 1989;van Oss 1994). It is interesting that the minimum of the contact angle occurs at the concentration of the surfactant mixture equal to 1 9 10 -6 M and the mole fraction of TX-100 equal to 0.2, at the constant surface tension of the solution.…”

“…The nylon-6 plate was prepared and cleaned according to the procedure described in the literature (Jańczuk and Białopiotrowicz 1989). The quality of its surface was controlled by a polarizing microscope (Nikon, ECLIPSE E 600 POL) and next the selected plates without cracks and roughness were additionally controlled by the contact angle measurements on the four sides of the water drop settled on the nylon-6 surface.…”

The contact angle measurements of the aqueous solutions of p-(1,1,3,3-tetramethylbutyl)phenoxypoly(ethylene glycol) (TX-100) and cetyltrimethylammonium bromide (CTAB) mixture with ethanol on nylon-6 were made in the range of the total concentration of CTAB and TX-100 mixture from 1 9 10 -6 to 1 9 10 -3 M and ethanol from 0 to 17.13 M. In the CTAB and TX-100 mixture the mole fraction of TX-100 was equal to 0; 0.2; 0.4; 0.6; 0.8 and 1. On the basis of the obtained results, the critical surface tension of nylon-6 wetting was determined from the dependence of cosine of contact angle and the adhesion tension as a function of the surface tension of the solution. This tension was compared to the components and parameters of nylon-6 surface tension taken from literature and discussed in the light of the surface excess concentration of the surface active agents at the nylon-6-solution interface calculated from the Lucassen-Reynders equation and the Gibbs isotherm.

“…These values are very close to each other, in particular in view of their variation on the method used to determine them. For instance, the interfacial energy of the glass/toluene interface can also be determined from the literature values of the surface tension of toluene (γ T = 29 mJ m −2 [45,46]), the contact angle of toluene on glass (θ = 6 • [46]), and the surface energy of glass (γ G = 48 mJ m −2 [47]), using Young's relation:…”

Thin polystyrene films were produced by spin coating from solutions in toluene. The amount of solvent retained in the films after drying for different times was measured using gas chromatography. Whereas for thicker films (thickness > 200 nm), the relative amount of solvent in the films is less than a few percent, the proportion of toluene increases significantly in thinner films. The thickness dependence of the mass of retained solvent shows that the solvent is mainly retained at the polymer-substrate interface. The solvent desorption rate exhibits no variation on the film thickness.

“…Of the four parameters of Young [26] were given by Fox and Zisman [27], Owens and Wendt [28], Janczuk and Bialopiotrowicz [29], Wu [30], van Oss, Chaudhury and Good [31], Li and Neumann [25], Kwok et al [32], Shimizu and Demarquette [33] and Chibowski et al [34]. Except for the Li-Neumann method, all the mentioned solutions use a pair or more liquids to calculate the surface energy of the solid and the interface solid-liquid.…”

Abstract:A new method, the sessile drop accelerometry (SDACC) for the study and measurement of the interfacial energies of solid-liquid-gas systems, is tested and discussed in this study. The laboratory instrument and technique -a combination of a drop shape analyzer with high-speed camera and a laboratory drop tower-and the evaluation algorithms, were designed to calculate the interfacial energies as a function of the geometrical changes of a sessile droplet shape due to the effect of "switching off" gravity during the experiment. The method bases on the thermodynamic equilibrium of the system interfaces and not on the balance of bi-dimensional tensions on the solid-liquid-gas contour line. A comparison of the mathematical model that supports the method with the widely accepted Young`s equation is discussed in this study.
