Abstract:
Understanding the interfacial adsorption of polymers has become increasingly important because a wide range of scientific disciplines utilize these macromolecular structures to facilitate processes such as nanoparticle assembly, environmental remediation, electrical multilayer assembly, and surfactant adsorption. Structure and adsorption characteristics for poly(acrylic acid) at the oil-water interface have been studied using vibrational sum frequency spectroscopy and interfacial tension to increase the comprehension of polyelectrolyte structure at interfaces. The adsorption of poly(acrylic acid) to the oil-water interface from the aqueous phase is found to be highly pH dependent and occurs in a multistep process, with the initial polymer adsorption displaying a high degree of conformational ordering.

Solubility
A solution is a homogeneous mixture composed of a solvent, the major component, and a solute, the minor component. The physical state of a solution—solid, liquid, or gas—is typically the same as that of the solvent. Solute concentrations are often described with qualitative terms such as dilute (of relatively low concentration) and concentrated (of relatively high concentration).
In a solution, the solute particles (molecules, atoms, and/or ions)...
