摘要：

PET/AlOOH nanocomposites have been synthesized via the in-situ method. The thermal degradation of PET/AlOOH nanocomposites in nitrogen was studied by thermogravimetric analysis (TGA) in order to obtain the activation energies of pyrolysis. The activation energies were determined by the Kissinger method which does not require knowledge of the reaction mechanism. The results showed that the value of activation energy of PET/AlOOH nanocomposites was higher than pure PET. Flame-retardancy was measured by the Cone Calorimeter (CONE). The results showed the heat release rate (ERR) of PET/AlOOH nanocomposites was distinctly lower than that of pure PET; the production of smoke was also lower than that of pure PET. The char of pure PET and PET/AlOOH nanocomposites were examined by scanning electron microscope (SEM). The char of PET/AlOOH nanocomposites was thicker than that of pure PET and the froth diameter of PET/AlOOH nanocomposites was smaller.
