Results indicate that properties of the composites are governed by ratio of the components: a form of cyclic voltammogram curves and location of specific ox-red polyaniline peaks strongly depend on the PAni amount. Gravimetric capacitance grows with polymer content in the material and reaches maxima 465 F·g-1 in 1M H2SO4 at discharge current density 0.2 A·g-1 for the sample with polyaniline content 60 wt %.
