Great caution must be exercised when applying the 1 CF2≈1.5 CH2 “rule” for surfactants: when grafted to a fluorinated chain, a hydrocarbon chain does not fully participate in micellization and adsorption processes, so these are controlled primarily by the length of the -CF2- chain. It is proposed that the hydrocarbon spacer adopts a folded conformation as a result of the difference in cross-sections between fluorocarbon and hydrocarbon chains.
