- Abstract:
-
Effects of chemical structure on adsorption and aggregation behaviour have been investigated for sodium perfluorononanoate (C8F17COO- Na+ or Na PFN) and 9-H perfluorononanoate (H-C8F16COO- Na+ or H Na PFN). Replacing the terminal F for H in this way gives rise to a permanent dipole moment at the hydrophobic tip of the chain. The critical micelle concentrations, determined by surface tension and electrical conductivity, were 10 and 40 mmol dm-3 for the Na PFN and H Na PFN, respectively. Tensio...
