Synthesis and Deposition of ICPs onto Electrode Surfaces

1 Synthesis and Deposition of ICPs onto Electrode Surfaces 

ICPs can be prepared through different chemical or electrochemical routes. However, it is evident that, when aiming to obtain a homogeneous film covering a conductive support, i.e., of an electrochemical device, the electrochemical approach craistitutes the most sprmtaneous and effective way to easily obtain the modified electrode. It also offers the advantage of a single-step process. 

To this aim, the electrode is immersed in a solution containing the monomer and a suitable supporting electrolyte it is then polarized at a suitable positive potential, where monomer oxidation occurs. The most widely accepted polymerization mechanism is represented in Fig. 2.2. 

Although many scientists have put enormous effort into studying how the electropolymerization-deposition process exactly occurs [2, 7, 9], some aspects 

When using a cyclic voltammetric technique (Fig. 2.3a), the potential is varied linearly from a value at which no electrode reaction takes place to a value at which monomer oxidation occurs. When the highest potential values are reached, the series of charge transfers, radical-radical coupling reactions, and p-doping take
