N2 - The composition and thermophysical properties of the composite aerogel of polytetrafluoroethylene with graphene oxide (PTFE-GO) before and after reduction with hydrazine vapour were investigated using X-ray photoelectron spectroscopy (XPS), thermogravimetry (TG), and differential scanning calorimetry (DSC). The reduction and subsequent heating at 370 °C, it was shown, increases the surface fluorine concentration and the thermal stability of the aerogel. The reduced sample has no weight loss associated with the pyrolysis of oxygen-containing functional groups in the temperature range from 95 to 230 °C. Nevertheless, the destruction of the polymer component even in the reduced aerogel begins at 400 °C, which is much lower than the temperature at the onset of thermal decomposition of bulk PTFE.
