Abstract:

The formation of nanoparticles by interaction of an anionic polyelectrolyte, sodium polyacrylate (NaPA), was studied with a series of oppositely charged surfactants with different chain lengths, alkyltrimethylammonium bromide (CnTAB). The binding and formation of nanoparticles was characterized by dynamic light scattering, ζ-potential, and self-diffusion NMR. The inner nanostructure of the particles was obsd. by direct-imaging cryogenic-temp. transmission electron microscopy (cryo-TEM), indicating aggregates of hexagonal liq. crystal with nanometric size.
