| Popis: | A water-soluble polyaramide "sulfo-invert-PPTA" surprisingly, already at a molecular weight of 10,000 g mol(-1), exhibits a nematic liquid crystalline phase in water at very low polymer concentrations, around 1-2wt%, indicating that supramolecular assemblies of molecules are the building blocks of the nematic phase. |
