Abstract: Abstract Non-stretched adenine-containing polyimide films based on pyromellitic dianhydride (PMDA) and adenine-containing diamine (p-APA) were prepared and annealed at various temperatures. IR studies indicated the existence of transformation of hydrogen bonding types from N-H⋯N (in… read more here.
