This Ph.D. study investigates the adsorption of monomeric (isostearic acid, ISA) and oligomeric fatty acids (poly(hydroxystearic acid), PHS 1400 and PHS 3500) to nanoparticles of industrial interest in carriers with different solvent properties. It was found that it was necessary to apply a number of methods to study the adsorption and subsequent stabilisation of the particles by the dispersing molecules, namely adsorption isotherm methods, rheological techniques, atomic force microscopy and UV/vis spectroscopy. The particles (surface) studied consist of uncoated titania and a commercially available titania coated with a combination of alumina and silica. The use of gel permeation chromatography (GPC) to study the adsorption behaviour of po...
