Figure 8.

Schematic depiction of (a) α-phase (left) and β-phase (right) of the crystalline chain conformation of PVDF. The arrows indicate projections of the -CF₂ dipole direction on planes defined by the carbon backbone.

Both the a- and c-axes are in-plane with the alumina surface and the b-axis, as well as the polarization axis P, are aligned with the long axis of the NWs. Reproduced with permission from [80].
