“…In the entire thickness range from 3 nm to 1 µm, the films are solid, without significant defects and/or pin holes. The polymer films were studied by atomic force microscopy (AFM) using earlier described methodology [5]. The study of the film morphology showed that they are homogeneous, and within the entire thickness range from 3 nm to 1 µm the films are solid, without significant defects and/or pin holes.…”

Polydiphenylenephthalide (PDP) belongs to the class of carbocyclic organic electroactive polymers, which exhibit electric conductive properties when an external electric field and/or mechanical stress is applied. In this work, the transport properties of thin-film layered lead–PDP–lead structures were experimentally studied in a wide temperature range. At sufficiently high temperatures, the current voltage characteristics are satisfactorily described in terms of the injection model of currents limited by the space charge. At temperatures below ~8 K, a number of samples exhibit features that can be explained by the effect of induced superconductivity in a thin film of conducting polymer enclosed between two massive superconductors (lead).

“…A model image of the structural unit of the PDP polymer is shown in Figure 1a . Polymers of this class are soluble in organic solvents and have exceptional film-forming properties [ 5 – 6 ]. According to these results, continuous homogeneous films can be obtained by centrifugation from a solution in cyclohexanone on a metal surface with a thickness from several nanometers up to micrometers.…”

Visualization of conducting channels in polymer layers by atomic force microscopy with a conducting probe

The results of an experimental study of the local electrophysical properties of ultrathin polymer films by atomic force microscopy with a conducting probe are presented. It is established that visualization of current flow sites (conducting channels) is possible in areas from which the surface layer has been mechanically removed. The conducting channels in the current image have the form of individual points with a height corresponding to the locally flowing current. It is found that the location of the observed channels correlates well with the model of conductivity along the grain boundaries of the supramolecular structure of the polymer. Keywords: thin polymer films, atomic force microscopy with a conducting probe, conducting channels, supramolecular structure.
