Synthesis and characterization of novel polyaniline/metal composites

The chemical synthesis of polyaniline (PANI) is explored using tetrachloroaurate, AuCl4- and hexachloroplatinate, PtCl 62-. These studies provide a simple method for the direct oxidation of aniline by these metal species and simultaneous formation of bulk quantities of PANI/Au and PANI/Pt composites, respectively. Studies of the PANI/Au composite indicate that the properties of the polymer are consistent with more traditional methods of preparation. The incorporation of metal into the polymer matrix shows an increase in conductance for the doped PANI/Au composite relative to PANI/HBF4 without Au particles. In the case of the PANI/Pt composite, the polymer is found to exist as an amine salt leading to diminished conductance for the doped PANI/Pt composite relative to PANI/HBF 4 without Pt particles. Most importantly, the data suggests that both metal dispersion and acid doping can be used to adjust the electronic properties of PANI.
