摘要：
A glassy carbon, P3, obtained by carbonization of polyfurfuryl alcohol was used to study the changes produced by oxygen plasma treatments which were compared to those obtained by molecular oxygen. The sample was selected for its well defined mesoporosity. The aim was to study the influence of porosity on the reactivity of the sample in oxygen plasma. The results were compared to previously reported data obtained using a glassy carbon with no macro or mesoporosity. It is concluded that the influence of mesoporosity is almost negligible in such a way that only the external surface was affected by plasma treatment. (C) 2000 Elsevier Science Ltd.
