Poly(vinylidene fluoride-trifluoroethylene) [P(VDF-TrFE)] copolymer films have been patterned by microimprinting with excellent quality of pattern transferring. Ferroelectricity of the imprinted films has been confirmed by ferroelectric hysteresis and surface potential measurement, and very good correlation is observed between remnant polarization and surface potential of the imprinted films. Imprinted P(VDF-TrFE) films show high remnant polarization and high poling-induced surface potential when the imprinting temperature is around 140 °C, suggesting that 140 °C is the optimal imprinting temperature for P(VDF-TrFE) films. The patterned ferroelectric P(VDF-TrFE) films can be used for a wide range of applications.
