Neutron reflection studies on reconstituted wax films interacting with non-ionic surfactant with/without solubilised pesticides

From deuterated and hydrogenated wheat waxes we have produced we here propose to use NR to study the structural features of the model wheat wax films formed on the C18 silane hydrophobed surface (self-assembled OTS). We will then study the adsorption and binding of nonionic C12E6 onto the wax film with and without solublised pesticide DP. By utilising careful isotopic variations, we aim to determine the equilibrated composition and structure of wax, C12E6 and DP across the interface, focusing on understanding the impact of the molecular interaction on the wax film structure in terms of component removal and structural features of the remaining films. The structural information from NR is unique and will well contribute to the understanding of transport of active agrichemicals across wax films. We request 4 days of Surf/Offspec time for completing this experiment.
