Abstract:

The interaction between the anionic surfactant, Na dodecyl sulfate, and the polyelectrolyte, poly(diallyldimethylammonium chloride), may give nanoparticles dispersed in H2O. The morphol. of the resulting nanoparticles and their ability to solubilize hydrophobic mols. were evaluated. As shown by SEM and AFM imaging, the particles are spherical, having a diam. of \~20 nm. The solubilization within the nanoparticles was tested with pyrene, a fluorescence probe, and Nile Red, a solvatochromic probe. For Nile Red the solubilization within the nanoparticles is at lower polarity than for SDS micelles, and from pyrene solubilization apparently the hydrophobicity of the nanoparticles depends on the ratio between the SDS mols. and the charge unit of the polymer.
