Synthesis of chemically and thermally advanced nonvolatile polyimide memorys |
| 초록 |
A new diamine monomer having carbazole group (HAB-CBZ) was prepared from 3,3′-dihydroxy-4,4′-diaminobiphenyl via consecutive reaction – phthalic imidization, Mitsumobu reaction and reduction, 3,30-bis[9-carbazole(ethyloxy)biphenyl]-4,40-diamine (HAB-CBZ) by polycondensation with four different aromatic dianhydrides: pyromellitic dianhydride (PMDA), 3,30,4,40-biphenyltetracarboxylic dianhydride (BPDA), 3,30,4,40-diphenylethertetracarboxylic dianhydride (ODPA), and 3,30,4,40-diphenylsulfonyltetracarboxylic dianhydride (DSDA). From the precursors, nanoscale thin films of polyimides (PIs) were prepared by spin-coating and subsequent thermal imidization. All the PIs exhibited excellent thermal and dimensional stability. In particular, the PIs based on the PMDA and BPDA units revealed excellent chemical resistance to organic solvents, in addition to the high thermal and dimensional stability. |
