A mechanism for the macroscopic charge balance during the transport of anions and cations across polypyrrole based composite membranes is proposed. For the mechanism to be studied, anions and cations were monitored simultaneously across PPy based composite membranes, which are known to have cation exchange (PPy(PSS)), anion exchange (PPy(ClO 4 )) and mixed ion exchange properties (PPy(pTS))...
The electrochemically synthesized conducting copolymer consisting of 3-octylthiophene and biphenyl units has been characterized by in situ resonance Raman spectroscopy, UV-visible spectroscopy, in situ FTIR attenuated total reflectance spectroscopy and cyclic voltammetry. The structure of the formed material is compared with the two homopolymers: poly(3-octylthiophene) or poly(paraphenylene). The...
