Conductive polymer matrices

Electrocatalytic reactions on chemically modified surfaces as well as on ionic-conducting polymer matrices are attractive new approaches and are being studied in various academic and industrial laboratories. Further work with such approaches is needed. 

Before detailing the main achievements in this area, it is noteworthy to discuss the physical properties and the preparation methods of the conducting polymer matrices which have been, or can be used, for the construction of modified electrodes with specific electrocatalytic properties. 

Successful incorporation of magnetic nanoparticles into a conductive polymer matrix will definitely widen their applicability in the fields of electronics, biomedical dmg delivery, and optics. These doubly functionalized nanocomposites will exhibit the magnetic properties of the magnetic particles and the conducting properties of the conductive-polymer matrices. However, one of the challenges so far is the abihty to integrate a high... 

A systematic materialization of functional molecules by their incorporation in the conducting polymer matrix was demonstrated by electrolytic polymerization of pyrrole, thiophene, aniline etc., in the presence of negatively charged functional molecules. This method is one of the most smart procedure to incorporate the functional molecule. The incoiporation of the functional molecules is driven electrostatically by the positive charges of the partially oxidized conductive polymer matrices through a doping process. When anionic...

The electronic properties of nanomaterials have stimulated significant interest due to possible applications in various filed. There is also interest in the enhanced conductivity that may be attained by imbedding nanomaterials in conducting polymer matrices [88-93]. As for example, four-point probe conductivity measurements of Au nanoparticles embedded in PPy, PANI, and PT demonstrate an increase of approximately two... 

Aside from the examples contained in Table 20.15, conducting polymer matrices have also proven to be a fertile area for the study of immobilized model redox species such as Fe(CN)6- " " [554-560]. Further, the immobilization of species such as glucose oxidase or glucose dehydrogenase [504,561-566], cytochrome c [567], and flavins [568] have laid the ground for the use of chemically modified conducting polymer films as sen-... 

Given the ability of incorporating nanoparticles into porous anodic films and conducting polymer matrices, with the latter forming within the pores, the incorporation of both TiOi nanoparticles and polyaniline in single step anodising is considered here. The corrosion performance of the coated aluminium alloy has been examined by salt spray testing and by electrochemical impedance spectroscopy. 

In the previous studies immobilization of polyphenol oxidase in different conducting polymer matrices was studied as an alternative method for the determination of phenolic compounds [23-25].
