The carbonization performance of the iron-containing carbon film resulting from polyimide was examined, Polyimide/Fe composite films were prepared from Iron (III) 2,4-pentanedionate (Fe(acac)) and poly(amic acid) (PAA) based on ODA and PMDA via a solution process in DMAC, followed by carbonization the polyimide film at a temperature range of 600–1600 °C. The organized polyimide/Fe combined fi lms were characterized using a scanning electron microscope (SEM), and thermogravimetric analysis (TGA), X-ray diffraction (XRD), and Raman. The formation of Fe particles and the synthesis of polyimide (PMDA/ODA) in the polyimide matrix is confirmed by FTIR results. Meantime, in the polyimide matrix, Fe particles were well spread which were showed by the SEM images. Kinetic parameters and thermal stability of the degradation methods for the organized polyimide/Fe combined films were examined in N 2 environment by TGA. The results have shown that the values of the calculated activation energies and thermal stability increased of the (Fe (acac)) the activation energy and loading also different with the weight-loss rate for all compositions.
