A conducting-grain picture is presented, based on the idea that the ion-polymer interaction process can be simply described as a rapid dissipation of the thermal energy converted from the kinetic energy in the ion track region. Thermal dissipation an

Recent studies of the electrical conductivity of heavy ion irradiated poly-ether-ether-ketone (PEEK) have shown that the conductivity of the highly damaged polymer is greater for ions of the greater electronic stopping power. The conductivity of the

Six new polymers containing imide and amide units, have been implanted by 50 keV Xe and 180 keV As ions. The measurements of surface resistance indicated that the conductivities of all polymers increased more than five orders of magnitude from their

Several kinds of polymers were implanted by 50 keV nitrogen (N + and N + 2 ) with different dose rates (0.16–2.03 μA/cm 2 ). The resistivity was measured using a constant voltage method. The dose rate was found to significantly influence the resis

Here we report work on the MeV irradiation adhesion modification of gold films on deposited tantalum pentoxide. For this system irradiation produces bubbling of the film at comparatively low doses, which in some cases leads directly to failure of the
