The image of the week

Let me present you the AFM image of the ferroelectric copolymer P(VDF-TrFE). The image below shoes the surface topography of a P(VDF-TrFE) thin film. There, it is possible to observe needle like structures and flat areas, corresponding to two different crystalline organizations: edge-on and flat-on crystals, respectively. This names relate to the way the polymer chain organiz s with respect to the supporting substrate.
