Effect of content on microstructure of PI/TiO2 hybrid Films

摘要：

A small-angle x-ray scattering (SAXS) technique using synchrotron radiation as the x-ray source has been employed to characterize the microstructure of PI/TiO3 hybrid films prepared by Sol-Gel method. It is shown that the SAXS profile is hardly constant with Porods law showing a negative and positive slope, suggesting that an interfacial layer exists between the nanoparticles and PI matrix in films when content of more than 5％. This suggests that the inorganic nanoparticles linked to the PI matrix through covalent bond. However, the only positive deviation exists in the film of content 5％. The reason is that there is a fluctuation of electron density in hybrid system. This kind of material has also been proved to possess both surface and mass fractal structures.
