Abstract
The features of creating supercapacitors based on anodic titanium-oxide nanotubes modified with a layer of a conducting polymer, i.e., the emeraldine form of polyaniline, are considered. Multilayer solid-state capacitive systems are formed based on nanostructured electrodes obtained by the anodic treatment of a titanium substrate in a solution of ethylene glycol and ammonium fluoride, followed by the deposition of a layer of polyaniline. Based on the analysis of voltammograms, the capacitance of nanostructured systems is determined to be 4.38 mF/cm2. The features of the influence of the structure of the anodic-formed oxide on the capacitance characteristics of the system are considered. It is established that as a result of the polymorphic transformation of amorphous anodic titanium oxide into crystalline titanium oxide during isothermal annealing, the voltammogram of the systems under study takes on a shape close to an ideal rectangular one, and the capacitance increases by a factor of 2. Based on the impedance-spectroscopy data of the studied samples, an equivalent circuit is constructed and the resistance and capacitance characteristics of the formed supercapacitors are determined.
