TLDR
In this paper, the effects of the alkyl chain length comprising even and carbon numbers have been examined in order to evaluate the surface free energy ΔGA-W and the standard free energy δGm for the micellization obtained from their surface tension data.Abstract:
Surface and micellar properties of a homologous series of Octaethylene glycol-n-alkyl ethers (CnE8;n = 9 to 15) have been studied in aqueous solutions by the surface tension measurements. The effects of the alkyl chain length comprising even and carbon numbers have been examined in order to evaluate the surface free energy ΔGA-W and the standard free energy ΔGm for the micellization obtained from their surface tension data. The areas per molecule and the equilibrium surface tension values at the CMC decreased with an increasing carbon number and they showed zigzag curves by the difference in even and odd carbon numbers.read more

Equilibrium and dynamic surface tension properties of partially fluorinated quaternary ammonium salt gemini surfactants.
TL;DR: It was confirmed that the kinetics of adsorption at the interface decrease with an increase in the fluorocarbon chain length and the concentration and the surface tension at the cmc decreased significantly; this surface tension value is lower than that of conventional fluorinated monomeric surfactants.

General relationships of the adsorption behavior of surfactants at the water/air interface
TL;DR: The structure of a surfactant is in direct correlation with the properties of an adsorption layer formed at a liquid interface as discussed by the authors, and the structure of surfactants can be predicted by using thermodynamic models such as the Frumkin, reori...
