Thermal Properties of Polyimide Film and Polyimide-Iron Composite Film

This study is on the thermogravimetric and the derivative weight loss of the Pi and Pi + Fe composite films. The weight loss resulted from the decomposition and burning. The peaks were observed and indicated the complete combustion of the Pi and Pi + Fe composite films. The prominent exothermic peak was observed at the Pi polyimide film at 550°C and the Pi + Fe composite film at 530°C, indicating the complete combustion of the films. The enhanced thermal stability of the polyimide synthesized with iron can be attributed to the inherent thermal stability of these materials and the robust chemical bonding interactions between the polyimide and iron.
