- Аннотация: Electroconducting hydrogels (EH) based on copoly(aniline - p-phenylenediamine) grafted to thepolyacrylamide for the application as pseudo-supercapacitor’s electrodes have been prepared.The influence of preparation conditions on the structure and capacitance properties of thesystems were investigated: we determined the optimal amount of p-phenylenediamine to obtainthe network of swollen interconnected nanofibrils inside the hydrogel which provides theformation of continuous conducting phase. Structure and morphology of the prepared sampleswere investigated with UV-VIS spectroscopy, scanning electron microscopy (SEM) and wideangle X-ray diffraction (WAXD). The maximal value of capacitance was 364 F g-1 at 0.2 A g-1. It was shown that the EH samples demonstrate the retention of 50% of their capacity at highcurrent density 16 A g-1. Cycle-life measurements show evidence that capacitance of EH electrodes after 1000 cycles is higher than its initial value for all prepared samples. Changes ofthe copolymer structure during swelling in water have been studied with WAXD.
