NMR and Morphology Analysis of LiClO4 Pseudoprotonated Polyaniline

This work reports on the study of polyaniline, doped with LiClO4 via pseudoprotonalion, by Nuclear Magnetic Resonance and morphology analysis. The 7Li NMR spin-lattice relaxation and linewidth investigations were performed for two different salt concentrations as a function of the temperature. The i...

Description
Summary:This work reports on the study of polyaniline, doped with LiClO4 via pseudoprotonalion, by Nuclear Magnetic Resonance and morphology analysis. The 7Li NMR spin-lattice relaxation and linewidth investigations were performed for two different salt concentrations as a function of the temperature. The increase of ion concentration strongly affects the relaxation processes. Information about electrical conductivity and thermal analysis are also reported.
