  • Abstract
    Annealing of thin copolymer films of vinylidene fluoride (VDF) and trifluoroethylene (TrFE) causes a strong increase in grain size as well as in crystallinity. It is known from AFM topographic images that flat-on lamella with diameters of up to 100 mum grow when thin films are annealed at temperatures around 140degC for several hours. To examine the orientation and the polarization state of the lamella, two dimensional images of the pyroelectric activity have been recorded.
