Mesomorphic solid-like structures of sulfated extra-cellular polysaccharide-C n TAB compounds Academic Article uri icon


  • Complexes formed by a partially sulfated polysaccharide (from the unicellular micro alga Porphyridium sp.) and surfactant homologues of alkyltrimethylammonium bromide were investigated using various techniques, such as small and wide angle X-ray scattering, optical phase interference microscopy and 2 H nuclear magnetic resonance (NMR). The scattering data suggest an average regular ordering at both microscopic and mesoscopic length scales, the second of which varies with the surfactant tail length. The 2 H NMR …
