In this research work, polyimides (PI) hybrids of Bis(4-aminophenyl)-1,4-diisopropylbenzene (Bisaniline P) and 4,4′-(hexafluoroisopropylidene) diphthalic anhydride (6FDA) were synthesized via chemical imidization and freeze-drying. The sample was in form of xerogels. The PI xerogels were mixed with mesoporous SiO2 hollow nanosphere particles (SHNP) synthesized by using polystyrene as template. The morphology and structure of materials were characterized through scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR).
