Nuclear magnetic resonance technique to distinguish between micelle size changes and secondary aggregation in anionic and nonionic surfactant solutions

摘要: The presence of surfactants in large micelles gives rise to broad n.m.r. resonances because the long correlation time for diffusion around micelle. This has been used investigate structure surfactant aggregates systems where other evidence indicates that occur. For polyethylene oxide at cloud point, are small and units formed by secondary aggregation micelles. sodium dodecylsulphate with added salt, octanol or surfactants, formed. changes micelle size indicated linewidths agreement measured quasi-elastic light scattering technique.
