Effect of Annealing Temperature on the Morphology and Piezoresponse Characterisation of Poly(vinylidene
fluoride-trifluoroethylene) Films via Scanning Probe Microscopy
Figure 3
Schematic structure of (a) edge-on (b) face-on lamellar structure for films annealed (a) below the melting temperature, (b) above the melting temperature. The red lines are representative of a single PVDF-TrFE molecular chain folding to form crystalline lamellae [15].
