Abstract: |
Using 3,3’,4,4’-biphenyl tetracarboxylic acid dianhydride(BPDA) and 3,4’-bis(m-aminophenyl) ether (3,4’-ODA) as monomers, three kinds of polyimide (PI) inorganic hybrid composite films including PI/SiO2, PI/AlN and PI/SiO2/AlN were prepared through the thermal imidization by means of the sol-gel reaction and situ-polymerization under supersonic methods. Their optical properties were characterized by ultraviolet- visible spectrum and X-ray diffraction spectrum. These experimental results indicated that the transmittance of three kinds of hybrid films descended with increasing inorganic component content. For PI/SiO2/AlN system, the transmittance of PI hybrid films drastic decreased due to the phase separation.
