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
