Tiivistelmä
Attracted by the increasing demand of batteries, sensors and supercapacitors, great efforts have been paid to the development of nanocomposite material with low cost, high energy density, high stability, easy processability.1 Polyaniline(PANI) is a special kind of electroactive conducting polymer, showing great electrochemical performance, such as redox reversibility and high conductivity 7. Besides, due to its environmental stability, low cost, and easy processability, PANI has been regarded as a potential material for flexible electronics and many researchers reported on it by interesting on the redox properties.
However, due to the structural instability, its cycling performance is still an insurmountable challenge. Reasonably designed nanostructured conductive polymers are considered to be the most promising materials to have high electrochemical performance 7. Nanocomposites of conductive polymers and metal oxides, especially transition metal oxides, can be used in catalysis, sensing, energy and other fields. Herein, PANI is combined with α-Fe2O3 nanoparticles by electropolymerization, and further studies on the properties of the nanocomposites are analysed by Cyclic Voltammetry(CV), UV-vis, FTIR, etc.
As a most standard electrochemical technique tool, CV described the performance of electrodes and characterize electron transfer. For CV, generally three electrodes are used to obtain accurate results. On the other hand, CV has key advantages which include quick operation time, low cost and simplicity in preparation 5. This study demonstrates the synthesis and properties of α-Fe2O3/polyaniline nanocomposite as high-performance materials in various applications. The overall analysis confirmed that the prepared α-Fe2O3/PANI nanocomposite material has better performance in terms of capacitance and conductivity in supercapacitors, batteries, etc.
