Abstract
Ferroelectric behavior was investigated for fluorinated polyurethanes with odd–odd or odd–even numbers of C atoms; poly(hexafluoro-1,5-pentane-heptamethylene dicarbamate) (5F,7 polyurethane) and poly(hexafluoro-1,5-pentane-hexamethylene dicarbamate) (5F,6 polyurethane). Remanent polarization and coercive field estimated from D–E hysteresis loops were 25—35 mC m−2 and 20—30 MV m−1, respectively.
