Bebon, Rick published the artcileElectrostatic pair-interaction of nearby metal or metal-coated colloids at fluid interfaces, Application of n-Octanol, the main research area is electrostatic pair potential colloid.
In this paper, we theor. study the electrostatic interaction between a pair of identical colloids with constant surface potentials sitting in close vicinity next to each other at the fluid interface. By employing a simplified yet reasonable model system, the problem is solved within the framework of classical d. functional theory and linearized as well as nonlinear Poisson-Boltzmann (PB) theory. Apart from providing a sound theor. framework generally applicable to any such problem, our novel findings, all of which contradict common beliefs, include the following: first, quant. and qual. differences between the interactions obtained within the linear and the nonlinear PB theories; second, the importance of the electrostatic interaction between the omnipresent three-phase contact lines in interfacial systems; and, third, the occurrence of an attractive electrostatic interaction between a pair of identical metal colloids. The unusual attraction we report largely stems from an attractive line interaction, which although scales linearly with the size of the particle can compete with the surface interactions and can be strong enough to alter the nature of the total electrostatic interaction. Our results should find applications in metal or metal-coated particle-stabilized emulsions where densely packed particle arrays are not only frequently observed but also sometimes required.
