Structure of Micelles in n-Alkanes

This section is based on Ref. [69] and will describe the structure of monoglycerol-based nonionic surfactant micelles in n-alkanes. The effects of solvent properties, temperature, the alkyl chain length of surfactant, surfactant concentrahon, and added water or glycerol will be mainly discussed. The glycerol a-monomyristate (G14G1) is taken as the main surfactant. 

Arrows and broken line in panel b highlight the maximum dimension, Dm , and core diameter of the micelles, respectively. 

Effect of Added Water or Glycerol The formation of reverse micelles and, hence, the existence of critical micelle concentration (cmc) in surfactant/oil binary systems is still a matter of open discussion. Surfactants usually do not form reverse 

Quantitative estimation of the cross-sectional diameters 1.9nm judged from the Dc max in pfr) of the G Gj in tetradecane and hexadecane systems are very close to the value estimated from the inflection point in the total p(r)-function and almost identical in all linear-chain oils (data not shown). Addition of water significantly increases the cross-sectional diameter of the micelles indicating the formation of water pool at the micellar core.
