Preliminary studies (34,35), which are described in the discussion, of the polymer and model con unds seem to indicate that, when the TANI-polyimide derivatives have nearly identical electrochemical and spectroscopic behavior as that of TANI. This would indicate that, when oligomeric aniline is "isolated within a polymer its behavior is unchanged over that of the discrete molecule in solution and bodes well... 

In this paper, recent results of studies performed on the imide derivatives of the trimeric aniline are presented. Films of TANI-polyimide were also prepared and their electrochemical and electrochromic properties were probed. It is shown from this work that well behaved polymeric materials incorporating aniline trimers can be prepared, these trimers can be addressed electrochemically within such polymeric systems and the behavior of the trimer within the polymer does not differ significantly from that within the model compounds. 

The corrosion protection properties of electroactive polyimide/clay nanocomposite (EPCN) coatings were investigated by a series of electrochemical measmements in 3.5wt% NaCl electrolyte. Gas barrier properties and redox behavior (i.e. electroactivity) of EPCN materials, in the form of membrane and coating, was identified by the studies of gas permeabihty analysis (GPA) and electrochemical cyclic voltarmnetry (CV), respectively.
