Abstract
This article analyzes how the individual structural elements of
surfactant molecules affect surface properties, in particular, the point
of reference defined by the limiting surface tension at the aqueous
cmc, γcmc. Particular emphasis is given to how the chemical nature and structure of the hydrophobic tails influence γcmc.
By comparing the three different classes of surfactants, fluorocarbon,
silicone, and hydrocarbon, a generalized surface packing index is
introduced which is independent of the chemical nature of the
surfactants. This parameter ϕcmc represents the volume fraction of surfactant chain fragments in a surface film at the aqueous cmc. It is shown that ϕcmc
is a useful index for understanding the limiting surface tension of
surfactants and can be useful for designing new superefficient
surfactants.
