We show the microstructures and ferroelectric domains of 200nm diameter poly(vinylidene fluoride-trifluoroethylene), P(VDF-TrFE) with composition of 75/25 mol%, nanorods fabricated by a porous template technique. In order to characterize the piezoelectric properties of P(VDF-TrFE) nanorods, both nanoscale manipulation and polarization switching were studied using piezoresponse force microscopy (PFM). Ferroelectric domains and their properties were confirmed using X-ray diffraction and PFM analysis. The ferroelectric domains in the nanorods were homogeneously switchable below 5V. This offers our rationale for a promise in energy harvesting and switchability would be good for plastic electronics.
