Synthesis and Characterization of Fully Aliphatic Polyimides from an Aliphatic Dianhydride with Piperazine spacer for enhanced Solubility, Transparency, and Low Dielectiric constant |
| 초록 |
A new fully APIs based on a movel aliphatic aliphatic dianhydride monomer-2,2’-(1,4-piperazinediyl)-disuccinic anhydride (PDA), in which two units of succinic anhydride have been connected by an aliphatic heterocyclic piperazine spacer that possesses amino-methylene(-NCH2) moiety in the aliphatic/alicylic backbone capable of inducing charge transfer(CT) interactions in the polyimide network, was successfully synthesized. The APIs were soluble in common polar organic solvents. The polyimide films of PDA with alicyclic diamines were almost colorless. T10 (temperature of 10% weight loss) of APIs were ranged from 299-418 ℃, Tg of API3-API6 were in the temperature range of 170-237 ℃, tensile strength of 54-72 Mpa, tensile strength of 54-72 Mpa, tensile modulus of 1.6-2.3 Gpa and elongation at break of 4-9%. The dielectric constant of one the synthesized API (API4) was as low as 2.14. The polyimide films of API3-API6 were highly flexible and freestanding which is quite rare in fully APIs. |
