ABSTRACT
I. INTRODUCTION Of all known intrinsically conducting polymers, polypyrrole is probably the one most frequently used in commercial applications, mainly due to the long-term stability of its conductivity and to the possibility of forming homopolymers or composites with optimal mechanical properties [1-5]. The preparation of soluble and processible polypyrroles, with an additional improvement in atmospheric stability, makes these materials serious candidates for use in technological applications, for example, for antistatic or magnetic shielding coatings [6-8], sensors and actuators [9-11], batteries [12-14], and molecular devices or modified electrodes [15-18].
