Film thickness and Ageing influences on Surfactant Distribution and Nanostructure in PVA Films

Abstract: Recent NR results (fig 1) have shown the ability to characterise surface segregation and nanostructuring of surfactants in PVA film. As well as the fundamental scientific interest, this behaviour is relevant to the ageing and performance of PVA film used in unit dose detergent products. Surface segregation will impact wettability and the ability to seal PVA films together and the nanostructuring is likely to alter the reversibility of surface segregation and the tendency for lateral migration. This experiment aims to better understand whether the surface segregation process is diffusion limited and kinetically trapped or reflects the equilibrium outcome for plasticised PVA film with surfactant. By exploring films that are thicker and contain lower surfactant loadings, not only do we approach more realistic formulations, but the systems are inherently slower to equilibrate.
