Polarized infrared attenuated total reflection for the in situ determination of the orientation of surfactant adsorbed at the solid/solution interface
Article Abstract:
Research was conducted to examine are determine the average orientation of the methylene tail of cetyltrimethylammonium bromide (CTAB) using polarized infrared attenuated reflection. Calculations were made of the methylene absorbance bands of CTAB adsorbing on silica in the S and P polarized states. Results indicate that surfactant desorption occurs in localized areas and that the residual surfactant is present in isolated clusters of highly ordered molecules that take a considerable time to relax their orientation.

Influence of electronic properties of naphthalene compounds on contact angles
Article Abstract:
An ideal pattern of contact angles can deviate the contact angles of a homologous series of naphthalene compounds on films of fluorinated acrylate polymers. The results show that the electronic properties of the compounds, like the electronegativity, the distribution of electrostatic charges and the rise of a dipole moment highly affect the contact angles.

Contact angle interpretation: combining rule for solid-liquid intermolecular potential
Article Abstract:
It has been possible to generalize a combining rule for intermolecular potential. This rule gives a good fit to experimental adhesion and contact angle patterns for the range investigated.
