A novel series of polyurethane-based polycarbonate diols containing fluorinated hard segments in the main chain (FPU) were synthesized using a prepolymer method. The fluorinated hard segment content was varied to study the effects on the dielec. and polarization behaviors under an applied elec. field (P-E loop). The addition of a fluorinated chain notably improved the polarization via an induced dipole moment in the PU films and higher dielec. constant, including allowing the relaxation peak to move to a lower frequency. Paraelec. loop behavior was observed with thinner loops as the fluorinated group content was increased. The nature of the solvent used for the synthesis affected the H-bonding capabilities and fluorinated group content. FPU synthesized in DMF showed a higher dielec. constant than that synthesized in dimethylsulfoxide due to its higher fluorine content.
