Hydrophobic Attraction

The energies and forces between contacting surfaces originate from the interaction forces between atoms and molecules. This chapter discusses how these atomic level forces lead to various types of force–separation relations as two surfaces are brought into contact. This chapter covers the interactions between atoms (repulsive atomic potentials and van der Waals interactions), the interactions within liquid and aqueous media (solvation forces, electrostatic double layer, hydration repulsion, hydrophobic attraction), and electrostatic interactions from contact electrification. Due to their ubiquitous effect on adhesion, van der Waals interactions are discussed at length, including examples for calculating adhesive forces in different geometries using Hamaker constants.

AbstractSolution behaviors of poly(styrene-co-sodium methacrylate) were studied by fluorescence spectroscopic methods using pyrene as a probe. The mol% of methacrylate was in the range 3.6–9.4. Water and N,N-dimethylforamide(DMF) mixture was used as a solvent (DMF/water = 0.2 mol %). The critical micelle (or aggregation) concentrations of ionomers and the partition coefficients of pyrene were obtained the temperature range 10–80°C. At room temperature, the values of CMCs (or CACs) were in the range 4.7 ×10-6 5.3 ×10-6 g/mL and we could not find any notable effect of the content of ionic repeat units within the experimental errors. Unlike CMCs, as the ion content increased, partitioning of pyrene between the hydrophobic aggregates and an aqueous media decreased from 1.5 ×105 to 9.4 ×104. As the temperature increased from 10 to 80 °C, the values of CMCs increased less than one order of magnitude. While, the partition coefficients of pyrene decreased one order of magnitude and the effect of the ion content became negligible.
