Microstructure of the hematite fibres (α-Fe2O3) obtained by the electrospinning process at three different flow rates of the precursor solution; 1,5 ml h^-1, 1,0 ml h^-1, 0,5 ml h^-1 and thermal processing at 700 °C, 1 h has been investigated. Using EDS, ATR-FTIR, XRD and UV methods it has been confirmed that the obtained fibres consisted only of α-Fe2O3. SEM images of the hematite fibres pointed out the fibre diameter / flow rate correlation, i.e. the slowest flow rate produced fibres with the smallest diameters. Electrical properties of α-Fe2O3 fibres have been examined using the four point probe method and the semiconducting properties have been confirmed using the Tauc model. Due to the low electrical conductivity of hematite the research was directed towards the formation of a composite material with enhanced electrochemical properties. A composite material α-Fe2O3/rGO has been obtained via a hydrothermal method using graphene oxide (GO) and olive leaf extract (ELM) solution with addition of hematite fibres (1,0 ml h^-1). This procedure was carried out at two different pH values; 4 and 10, and as a result composite hydrogels were obtained. In addition to this, for each composite sample a reference hydrogel without hematite fibres was synthesised, rGO. Morphological, structural and electrochemical characterizations have been conducted for the composite (α-Fe2O3/rGO) and reference (rGO) samples. SEM and XRD results confirmed the incorporation of the hematite fibres into the composite material as well as a partial prevention of the rGO sheet agglomeration. In order to carry out electrochemical measurements 6 symmetrical supercapacitors have been assembled and tested by means of cyclic voltametry (CV), electrochemical impedance spectroscopy (EIS) and chronopotentiometry. The obtained results showed a positive effect of the α-Fe2O3 fibres on capacitive properties of the composite material.
