Synthesis and properties of PI-silica composites containing silane coupling agent |
| 초록 |
Polyimides (PI) are generally classified as thermally stable polymers due to the excellent mechanical strength and the thermal. Silica has been most investigated as an inorganic filler for the composites because of improvement in the thermal and mechanical properties. The PI-silica composites were prepared from poly(amic acid) (PAA) solution as precursor. Pristine PI and PI-silica composites could be obtained via thermal imidization of PAA produced with BPDA and ODA in DMAc. The content of silica in the composites was 1, 3 and 5 wt% with the use of silane coupling agent (SCA) to improve dispersion of silica in the matrix. And the thermal imidization of PAA in composites was heated for 1h at 100℃, 30 min at 200℃ and 1h at 350℃ to adapt PI form. The PI-silica composites were characterized with thermal, mechanical and morphological properties. The results demonstrated that the addition of small amount of silica and SCA led to the improvement in thermal and mechanical properties. |
