| Abstract: | A series of polyimide/silica nano composite materials with different silica contents were prepared through the sol gel method by gelation of polyamic acid (PAA) and hydrolyzed tetraethoxy silane (TEOS) in the existence of a coupling agent.TGA and DSC were employed to evaluate the thermal properties of the materials. The results show that both degradation temperature (T d) and transition temperature (T g) of the hybrids increase with the increase of SiO 2 contents.It is thought that this is attributed to the addition of an inorganic matrial SiO 2 to the organic polymide. |
