Filled and unfilled EPDM rubbers were contaminated with two different particle sizes (50 /spl mu/m and 165 /spl mu/m) and different particle concentrations, to ascertain their influence on the breakdown strength. The inclusions were irregularly shaped iron particles. The breakdown tests were carried out by using /spl sim/0.7 mm thick circular rubber slabs between cylindrical electrodes. The result yielded the characteristic AC breakdown strengths of 78 kV/mm and 86 kV/mm respectively for non-contaminated filled and unfilled rubbers. The electric strength was considerably lowered for larger inclusions but not in the case of smaller ones. A statistical evaluation of the results is also provided.","PeriodicalId":13148,"journal":{"name":"ICSD'98.

The experimental results indicate that the electron/hole injection into the new functional organic layer from the electrodes are influenced by the Fermi level of the electrode material. We will discuss the electronic behavior of the localized energy states of the new functional organic layer based on the measurement of the internal phenomena.","PeriodicalId":13148,"journal":{"name":"ICSD'98.
