Thermal stability analysis. (a) TGA curve of AFA-E expressed as weight percentage (left side) and its first derivate (right side) in the range of temperature between 30 and 800°C. (b) Isothermal thermogravimetric analysis of AFA-E sample at 220°C (blue area) followed by a nonisothermal thermogravimetric analysis (pink area) from 220°C to 800°C at the rate of 10°C/min as a function of the time.
