- 論文の詳細を見る
Polyimide (PI) was successfully hybridized with silica and PDMS by synchronizing two reactions; imidization of poly(amide acid) (PAA) and sol-gel reaction of tetraethoxysilane (TEOS) and diethoxydimethylsilane (DEDMS). TEOS and DEDMS were used as precursors for the formation of silica and polydimethylsiloxane (PDMS), respectively. The progress of sol-gel reaction was confirmed by IR. It was revealed from the study of scanning electron microscopy that silica has better compatibility than PDMS. The effect of the silica and PDMS on the mechanical and thermal properties of the hybrids was studied. Hybrid containing 3-5 wt% of silica and 3-5 wt% of PDMS gave the highest tensile properties. Dynamic viscoelastic analyses and thermogravimetric analyses revealed that thermal properties were improved by the hybridization.
