Abstract : Thin organic insulator films were prepared by an improved Langmuir film technique, by evaporation and by interfacial polycondensation. Barium and calcium stearate, stearic acid, hexacosanoic acid and polyvinyl benzoate (PVB) monolayers were transferred by the Langmuir method, and the electrical properties of these films, sandwiched between evaporated electrodes of various metals, were studied. Monolayers were successfully transferred only onto chemically active substrates, such as Sn or Cu. With these electrodes, the conduction process through mono-and multilayer films is described in terms of a combined tunneling and Schottky-emission mechanism, with an activation energy of 0.25 eV. Gamma ray irradiation and autoradiographic studies on films of PVB were made. Evidence for radiation-induced cross-linkage was obtained for bulk PVB. It was concluded that the stable monolayer of PVB is composed of 3-4 interlocking layers of molecules. Some interesting memory effects were observed in sandwiches formed with PVB.
