Abstract

The sharp and broad electron spin resonance (ESR) signals from nanocomposites of conducting polypyrrole with inorganic clay were synthesized. A sharp ESR signal with 1D characteristics was observed, which originated from the weak spin-orbit interaction of the intercalated and well-ordered nanolayers between the clay layers. It was found that the broad ESR linewidth of the nanocomposites was due to the polarons in the bulky conducting PPy parts enclosed in the clay particles. It was also found that the coulomb interaction between the positively charged polymer backbone of the intercalated nanolayers enhanced the thermal stability of the clay samples.
