Various applications of ion beam bombardment to the surface treatment of polymer have been studied. The effect of bombarding the polyvinylchloride films with a beam of argon ions and of CO2 ions for different ion currents and accelerating voltages are compared with the extraction of the surface layers of so-called the blocking test which has been done by thermal treatment (70 °C) at the pressure (10 kg/cm2) between the copy paper and plastic sheet. Also, the sheets deposited with carbon layers sputtered by ion beam bombardment is examined. It is found that both ion beam bombardment (with argon ions and CO2 ions) and ion beam sputter deposition (with carbon) are very useful to block an addition diffused from the inside to the surface among the polymer and sheets treated by ion beam bombardment (sputtering and deposition) are useful to block the surface diffusion for secular variation. Polymer surface treated by ion beam bombardment can be used to remove polymer surface layer under the non-thermal working state.
