| | Polyimides with Fluorenyl Side Groups and Their Unusual, Unique Alignability of Liquid Crystals at the Film Surface | | Authors: | S.G. Hahm, T.J. Lee and M. Ree | | Affilation: | Pohang University of Science and Technology, KR | | Pages: | 297 - 300 | | Keywords: | liquid crystal (LC) alignment, polyimides | | Abstract: | Polyimides (PIs) have been widely used in the microelectronics industry as dielectric materials because of their advantageous properties. In the present study, we synthesized CBDA-FDA and its analogue, poly(4,4’-(9,9-fluorenyl)diphenylene pyromellitimide) (PMDA-FDA) and then investigated quantitatively the orientational distributions of the polymer chain segments in the surfaces of their films by using linearly polarized FT-IR spectroscopy and optical retardation analysis | | ISBN: | 1-4200-6182-8 |
