Mechanochemical synthesis of polyaniline in the presence of polymeric sulfonic acids of different structure

- Polyaniline/polysulfonic acids complexes can be prepared mechanochemically.
- Mechanochemical synthesis results in the dramatic change of UV-vis-NIR spectra.
- Mechanochemical synthesis results in the increase of conductivity.
- Rigidity of the polysulfonic acid backbone influences the complexes structure.
- Conductivity increase is due to intensive π-π-interactions between PANI-chains.
