Figure 3

Atomic force microscopy (AFM) surface morphology images of PVDF thin films (20 × 20 μm2). Comparison between PVDF bulk, with (a) drop-cast; (b) drop-cast-TT, and the MAPLE-deposited samples at different fluences: (c) 1.0 J/cm2, (e) 1.3 J/cm2, (g) 1.5 J/cm2. In addition, the thermally-treated variant of the MAPLE-deposited films at (d) 1.0 J/cm2 + TT, (f) 1.3 J/cm2 + TT, and (h) 1.5 J/cm2 + TT.
