WebFeb 22, 2024 · The derivative TGA curves of graphene oxide, FLG, and graphite powders have distinct peaks with a temperature of maximum mass decomposition rates (Tmax) in specific ranges, which can aid in distinguishing few-layer graphene from fake graphene. Thermogravimetric Analysis for Nanoparticles WebThe TGA curve of PVDF hollow fiber has essentially no weight loss before 453.2°C. The fastest decomposition temperature is 463°C (the peak temperature corresponding to the DTG curve). At the temperature of 778.3°C, the PVDF hollow fibers do not lose weight anymore. The same result is also found in the DTG curve.
