  • Effect of Acidity on the Size of Polyaniline-Poly(sodium 4-styrenesulfonate) Composites Particles and the Stability of Corresponding Colloids in Water

  • The practical application of polyaniline-poly(sodium 4-styrenesulfonate) (PANI–PSS) composite particles has been held back by the low stability of their dispersed state in water. In this work, we present a general oxidation approach to prepare PANI–PSS composite nanoparticles that can form highly stable colloids in water or buffer over a wide range of pH from 1 to 11. We demonstrate that the size of the PANI–PSS composite particles can be controlled by the acidity of precursor solutions. It is hypothesized
    that the number of negatively charged sites on PSS, which can be affected by the acidity of the precursor solutions, plays an important role in determining the size of the PANI–PSS composite particles and the stability of corresponding colloids in water.
