Abstract
A variety of two-dimensional microscopic structures resembling emulsions and other colloidal forms have been reported in spread and adsorbed monolayers at fluid interfaces. These two-dimensional colloids may be described as the mutual dispersion of first-order co-existing surface phases associated with the linear tension between the phases, in a manner analogous to the role of surface tension in the dispersion of three-dimensional phases. A formal description of linear tension in monolayers is given, and several relationships, notably the one-dimensional analogues of the Gibbs adsorption isotherm and Kelvin equation, are discussed in the context of potential new experiments. The discussion is primarily for spread insoluble monolayers. The limitations of the utility of the linear tension concept are also considered.
