METHOD FOR PERFORATING CARBON NANOMATERIAL, AND METHOD FOR PRODUCING FILTER MOLDED ARTICLE

摘要

The present invention addresses the problem of forming holes each having a desired size in a carbon nanomaterial to be used in filters, e.g., graphene, a carbon nanotube and a carbon nanohorn, uniformly and with high accuracy. A method for perforating a carbon nanomaterial to form holes each having a desired size in the carbon nanomaterial. The method is characterized in that the carbon nanomaterial is held in oxygen-containing air at 160 to 250ºC for a predetermined period of time while heating at a lower temperature. In the method, holes each having a desired size can be formed uniformly in the carbon nanomaterial by controlling the length of time for the heating.
