摘要：

This work reports on the study of polyaniline, doped with LiClO4 via pseudoprotonation, by Nuclear Magnetic Resonance and morphology analysis. The Li-7 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.
