abstract = {Small-angle neutron scattering has been used to probe the
interfacial structure of foams stabilised by small molecule
surfactants at concentrations well below their critical
micelle concentration. The data for wet foams showed a
pronounced Q−4 dependence at low Q and noticeable
inflexions over the mid Q range. These features were found
to be dependent on the surfactant structure (mainly the
alkyl chain length) with various inflexions across the
measured Q range as a function of the chain length but
independent of factors such as concentration and foam
age/height. By contrast, foam stability (for C < CMC) was
significantly different at this experimental range. Drained
foams showed different yet equally characteristic features,
including additional peaks attributed to the formation of
classical micellar structures. Together, these features
suggest the dynamic air–water interface is not as simple
as often depicted, indeed the data have been successfully
described by a model consisting paracrystalline stacks
(multilayer) of adsorbed surfactant layers; a structure that
we believe is induced by the dynamic nature of the
air–water interface in a foam.},
