To measure the Al-polymer (PTFE, PP) peel strength, the plasma polymerization was performed using a plasma reactor (Ilmplasma 1200 Saskia, Ilmenau, Germany). Then, the plasma polymer coated polymer samples were transferred into a separate electron beam metallizer (Auto 306 Edwards, UK). The thickness of deposited aluminum layers was adjusted to 150 nm using a quartz microbalance. [Pg.272]


Discuss the paradox in the wettability of a fractal surface (Eq. X-33). A true fractal surface is infinite in extent and a liquid of a finite contact angle will trap air at some length scale. How will this influence the contact angle measured for a fractal surface ... [Pg.382]

The simplest choice v /(Q) = where p is a half-odd integer and 4> is an angle measured around the degeneracy, is therefore nonnally employed in molecular Aharonov-Bohm theory. [Pg.27]

B = outlet diameter or width, g = acceleration owing to gravity, m = 1 for circular opening and 0 for slotted opening, and 0 = hopper angle (measured from vertical) in degrees. A modification of this equation takes particle size into account. This modification is only important if the particle size is a significant fraction of the outlet size (8). [Pg.556]

The atropoisomerism of N -phenylazoles, i.e. an isomerism of the type shown by biphenyl derivatives, has been studied by several authors. Some torsional angles, measured by X-ray crystallography (Section 4.04.1.3.1) are shown in Table 26. [Pg.210]

Two measured ellipsometric angles T and d at a fixed wavelength and a fixed angle of incidence enable calculation of a maximum of two other properties, e. g. the film thickness and refractive index of a transparent layer. Multiple angle measurements increase the number of measured quantities and hence the number of properties which can be determined for a specific sample, although even under these condi-... [Pg.266]

The technique of contact mechanics has also been applied to the direct mechanical determination of solid-fluid interfacial energies, and the results compare favorably with those obtained by contact angle measurements [19]. [Pg.9]

It should be noted that one may obtain an estimate for the surface energy of a solid from a single contact angle measurement by combining Eq. 9 or Eq. 11 with Eq. 3. One then has ... [Pg.23]

Section 4.1 briefly describes some of the commonly employed experimental tools and procedures. Chaudhury et al., Israelachvili et al. and Tirrell et al. employed contact mechanics based approach to estimate surface energies of different self-assembled monolayers and polymers. In these studies, the results of these measurements were compared to the results of contact angle measurements. These measurements are reviewed in Section 4.2. The JKR type measurements are discussed in Section 4.2.1, and the measurements done using the surface forces apparatus (SFA) are reviewed in Section 4.2.2. [Pg.80]

Surface energies determined by SFA and comparison to surface energies inferred from contact angle measurements (in mJ/m )... [Pg.114]

The surface energy of the solid can be obtained from equilibrium contact angle measurements of a series of test liquids on the solid surface, providing the relationship between ysi and the solid yg (in vacuo) and liquid yiv surface energies is known. The exact relationship is given by the Good and Girifalco equation [13,14] ... [Pg.322]

The surface forces apparatus (Section 2.3) enables the estimation of a surface energy term, Fq (Eq. 9), providing sufficiently smooth surfaces can be produced. In recent years Chaudhury, Pocius and colleagues have made a valuable contribution to the field of adhesion by developing the technique to study energies of adhesion and of surface energies of polymers [81-85]. These SFA results provide alternatives to values based on traditional destructive tests or contact angle measurements. [Pg.340]

G() is related to the reversible work of adhesion obtained using contact angle measurements, but in general is greater than W. This is because once an interface is formed and the adhesive solidifies, strain energy is required to mechanically disrupt the interface. This strain energy arises because of the physical connection between the attachment sites between the adhesive and the substrate and the connectivity between this interface and the adhesive bulk. [Pg.449]
