Abstract :
We showed oriented crystallization of ferroelectric nanofibers of P(VDF-TrFE) in nanoporous templates after melt wetting. 2D-PFM imaging and local poling of homogenously polarized domains with orientations inclined to the nanofiber long axis demonstrates how the oriented crystal growth restricts the possible orientation directions which can be address by local domain switching.
