Preparation and Characterization of Nanoporous Thin Films of Alicyclic Polyimides. |
| 초록 |
It is required to develop insulating materials with low dielectric constants for achievement of high integration and speed in semiconductor. In this work ABA-type triblock copolymers consisting of an aliphatic polyimide block and a thermally labile polymer block have been prepared from an alicyclic dianhydride, four alicyclic diamines, and an amine-terminated poly(propylene glycol) (PPG). Rel-[1S,5R,6R]-3-oxabicyclo[3,2,1]octane-2,4-dione-6-spiro-3’-(tetrahydrofuran-2’,5’-dione) (DAn) was used as the alicyclic dianhydride. The thermal properties of the copolymers were investigated by thermogravimetric analysis (TGA) and differential scanning calorimetry (DSC). Thermal decomposition of the labile block in the copolymers was carried out to obtain porous polyimide films, which were characterized with a scanning electron microscope(SEM). |
