Towards a mechanistic understanding of additive competition and adsorption at the particle interfaces in non-aqueous dispersions
This PhD project is in collaboration with Infineum. Infineum produce fuel and lubricant additives for transportation. The function of lubricant additives is to prevent damage to engines (e.g. abrasive and corrosive wear) and to confer beneficial properties (such as reduced emissions into the environment and improved fuel economy). A lubricant can, in many ways, be considered a mixture of surfactants, particles and polymers. The project focuses on the interface between soft matter and particles in the presence of complex surfactant systems. The aims of the project are to identify and provide mechanistic understanding of additive competition and adsorption at the solid (particle) interface as a function of (non-aqueous) solvent polarity. This project will result in the development of optimised oil formulations to improve fuel economy and provide enhanced environmental benefits.
The project will utilise NMR methodology, in particular, solvent relaxation, pulsed-gradient spin-echo NMR (PGSE-NMR) provide mechanistic understanding of the interactions between the various amphiphilic additives. These studies will be supplemented by small-angle neutron scattering experiments
