Nuclear magnetic resonance (1H NMR) spectra were registered in D2O on Varian Unity Plus 500 MHz spectrometer. The Fourier Transform Infrared (FTIR) spectroscopy analysis was carried out in order to confirm successful functionalization of C60 fullerene with PEG. The samples were prepared as KBr disks and the measurements were performed using the Shimadzu 8400S spectrometer. The thermal stability of investigated samples was assessed by thermogravimetric analysis (TGA) using Q50 TGA (TA Instruments). The analyzed samples were previously dried under vacuum at 60 °C and the measurement was carried out under flow of nitrogen with heating rate of 10 K/min. In turn, electrochemical properties were evaluated using cyclic voltammetry. Cyclic voltammogram for PEG-functionalized fullerene was recorded at room temperature on Autolab PGSTAT 204 potentiostat, with three electrode arrangement: GC electrode (3 mm diameter) as working electrode, Ag/AgCl as the reference electrode and platinum wire as the counter electrode. The 0.1 M Bu4NPF6 in o-DCB:acetonitrile (3:1, v/v) was used as the supporting electrolyte solution.

At each position, 40 scans were averaged. Spectra were baseline corrected and normalized to the highest peak (set to 1.0). To assess the spectra, only the area between wavelengths 500 to 2000 cm−1 was examined as this region includes the most informative values for lignocellulose materials.
