چکیده
|
In this study, polyanilinegraphene composites with different nanostructures are synthesized and the behaviour of the obtained composites serving as electrode materials in electrochemical capacitors is studied. the morphology, crystal structure, and thermal stability of the composites are examined using scanning electron microscopy (sem), x-ray diffraction (xrd), and thermal gravimetric analysis (tga). electrochemical properties are characterized by cyclic voltammetry (cv). according to the results, the obtained composites show different crystal structures and different thermal stabilities, and consequently different electrochemical capacities, when used as electrodes in electrochemical capacitors. a nano-fibre composite is shown to have a good degree of crystallization, 5.17% water content, 637°c degradation onset temperature, and 379 fg^-1 electrochemical capacity.
