Conducting Electronic Polymers by Non-Redox Processes
Abstract
The chemical composition and the IR spectra of both the New and ARA undoped forms of BASF (CH)x either oriented, or non-oriented have been examined. Even after extensive washing (up to 5 days) and/or after treatment with CH3OH/ HC1, relatively large amounts (up to approx 5%) of Titanium, ALuminum and Silicon residues remain in the film. This is consistent with their infrared spectra, which show strong vibrations characteristic of sp3-hybridized carbon believed to be associated primarily with the Ti(n-OBu)4 catalyst. The conductivity of the I2/CC14-doped films varies greatly from one portion of a film to another. For example, a non-oriented doped ARA film (elemental analysis: Residue approx. 4.6%; exhibited (sigma 15 determinations) a sigma (max) approx 8100, sigma (min) 500, sigma (av) 940, sigma (median) 880S/cm. Strongly- adhering, transparent, cohesive films (approx. 0.1 microm) of polyaniline (emeraldine.HC1) and also its N-substituted derivatives can be deposited on a variety of substrates such as gass, nylon, metals, AgC1 pellets, etc. from aqueous solutions of the corresponding anilines, HC1 and (NH4)02S2O8 during the initial stages of polymerization.
