Abstract :
Polyaniline doped with camphor sulfonic acid (PANI-CSA) has been shown to yield a material which, after processing from solutions in meta-cresol, exhibit a temperature independent magnetic susceptibility down to 50K. Below 50K a Curie like contribution sets in. We also report 13C NMR experiments was cleary show that the 13C spin lattice relaxation rates obey the Korringa relation for relaxation via the hyperfine coupling to conduction electrons.
