Abstract

We have studied the effect of oxygen ion bombardment of glassy carbon at room temperature, using a composite bi-energy beam of 3.2 and 3.1 MeV ions. Carbon specimens were prepared in-house by pyrolysis of phenolic resin at 1000° C. Raman microprobe spectra of the surface and implanted volume before and after irradiation showed that the implanted oxygen ions had disrupted translational symmetry at the surface and caused maximum damage in the carbon 3.5 μm below the surface. By analogy to the “activation” of charcoals1 we conclude that pores are opened up by preferential attack of strained carbon sites.
