The oxidative polymerization of pyrrole in montmorillonite clay is followed in real time using in situ FT-IR-ATR spectroscopy. A conducting polymer-clay composite is formed as the ferric sites present at the accessible surfaces of the clay particles chemically oxidize the aromatic heterocycle. The i...
