Abstract

We report strong experimental evidence on the formation of a molecular lyotropic phase in water of a modified polyaramide, namely a fully sulfonated poly(p-phenylene terephthalamide) (Sulfo2PPTA) that exhibits similar liquid crystalline behaviour in water to its non-sulfonated counterpart (PPTA, commercially known as Kevlar or Twaron) in sulfuric acid.
