Solution and Interfacial Properties of Cyclic Containing Anionic Surfactants

Deeming, Laura LU (2025)
Abstract
The bulk micellar and surface adsorption behaviour of a bio-derived cyclic-containing anionic surfactant, sodium tetradecyl furan sulfonate (STFS), has been studied in this work. To determine its viability as an alternative to petrochemically derived surfactants in detergents, the self-assembly and
adsorption properties were measured both alone and in binary and ternary mixtures with a common anionic and non-ionic surfactant. A combination of surface tension and neutron reflectometry at the air-water interface were used to determine the surface behaviour whilst small-angle neutron scattering was
employed to characterise micellar behaviour. Additionally, the role of differing aromatic rings (benzene versus furan) in the surfactant... (More)

A combination of surface tension and neutron reflectometry at the air-water interface were used to determine the surface behaviour whilst small-angle neutron scattering was
employed to characterise micellar behaviour. Additionally, the role of differing aromatic rings (benzene versus furan) in the surfactant head group and their effect on the micelle packing and water structuring around the head group was studied using Empirical Potential Structural Refinement (EPSR) combined
with total neutron scattering experimental data. (Less)
