Název v původním jazyce

Poster:A study of potentiodynamically controlled ionic exchange in the polypyrrole film (1)

Popis výsledku v původním jazyce

Polypyrrole (PPy) is one of the most studied conducting polymers. This is because it can be easily prepared and it has good mechanical properties, chemical resistance and high electrical conductivity. During PPy synthesis the anions of the basic electrolyte are inserted into the polymer structure. Subsequent polarization leads to ionic exchange between the solution and polymer. Mechanism of this transport is not clear yet. Widely accepted theory exists, that anions are preferably inserted/expelled during subsequent polarization. Only in the case of the large anions fixed sterically in the film structure the cations are forced to move instead. The aim of our study is to have a closer look on this problem and possibly to determine the real fraction of the anions and cations which participating on an ionic exchange between polymer matrix and electrolyte.Electrochemical Quartz Crystal Nanobalance (EQCN) has been choosen to accomplish this task. The reason is high sensitivity and fast respo
