Adsorption to Biomimetic Thiol Surfaces
The boundary of hair is formed by a lipid layer whose main component is the branched 18-methyl eicosanoic acid. How the lipid density and the amount of methyl branching affect the interaction properties of hair is not fully understood, given also the difficulty of direct study of hair. Such knowledge, though, is crucial for the design of products with protective and restorative properties, particularly in the current climate where there is an urgent need for new, sustainable materials to replace conventional additives which had years of optimisation. Adsorption models for coadsorbing polymers and surfactants to lipid surfaces based on Self-Consistent Field Theory exist, but these models require experimental verification and refinement. Neutron reflectance provides the ideal experimental window to understand how the unique branching of hair lipids affects self-assembly and adsorption in water. It is ideal for understanding hierarchical adsorption, where deuteration will provide the contrast.
