- Abstract
- We report the self-polarization alignment without external poling in spin-coated poly(vinylidene fluoride-co-trifluoroethylene), P(VDF-TrFE), thin films on transparent and flexible substrates. Piezoresponse force microscopy (PFM) allows the quantitative analysis of preferentially aligned polarization in the ferroelectric thin films. We found that as-received P(VDF-TrFE) thin films on transparent poly(3,4-ethylenedioxythiophene): poly(4-styrenesulfonate) (PEDOT:PSS) electrodes showed stronger self-polarization alignment than those on indium-tin oxide (ITO) electrodes. The relative ratios for the aligned polarization per unit volume on PEDOT: PSS and ITO electrodes were 18.6% and 4%, respectively.
