Abstract：The key to the study on the regularity about the mechanical,thermology and electricities property of the inorganic nano-mingled organic composition thin film is to understand the incorporated quantity,the particle size and distribution of nano-inorganic matter in the membrane quickly and accurately. In the present paper,the chemical structure,surface morphology and the actual content of nano-Al2O3 of the nano Al2O3-composite film of polyimide were characterized by X-ray atomic fluorescent spectroscopy(XRF),Fourier transform infrared spectroscopy (FTIR),scanning electron microscopy (SEM) and atomic forced microscope (AFM). The results are that the organic phase of PI and the inorganic phase of Al2O3 formed a complex composite hybrid system of bond-to-bond pattern,the nano-Al2O3 particles in the film of PI are dispersed homogeneously,and the diameter of the particle is smaller than 50 nm；the weight content of Al2O3 is 7.9% by XRF. The approach we used is an effective way of analyzing the inorganic component of the organic composite film materials doped with the inorganic nano-phase materials with the merits of no pretreatment,no fed charge (for analysis of insulation materials),no-contagion,no destruction,high speed and high accuracy,etc.
