EFFECT OF THE ELECTROLYTE NATURE AND CONCENTRATION ON THE MORPHOLOGY AND ELECTRICAL PROPERTIES OF ELECTROPOLYMERIZED NON-CONVENTIONAL POLYMER NANOTUBULES

摘要

The influence of some experimental conditions on the kinetics of electropolymerization of several monomers and the resulting morphology of the nanomaterials has been studied. The investigated monomers were: 1.2-, 1.3- and 1.4-phenylenediamine, 2.3-, 1.5- and 1.8-diaminonaphthalene, o- and p-anisidine, 5-amino-l-naphthol and o-, m- and p-aminophenol, and 3.3'-diaminobenzidine. In particular, the resulting polymers showed that an increase of the ionic strength values increases the polymerization rate at a constant potential, both in buffered solutions and also in acidic medium. Finally the morphology of the different template-synthesized nanostructured materials has been carefully analyzed by scanning electron microscopy (SEM). In addition, emission and Raman spectroscopy showed that the relative conjugation length increases with decreasing pore size.
