摘要：

Hexagonally-arranged porous carbon films (HaPCFs) were prepared by proton beam irradiation and carbonization of hexagonally-arranged porous polystyrene films (HaPPSFs). HaPPSFs prepared by an improved phase separation method were irradiated with 150-keV proton beam at a fluence of 4 x 10(16) ions cm(-2) to enhance the thermal stability for high-temperature carbonization. Proton beam irradiation of HaPPSFs was found to induce crosslinking and surface oxidation reactions. The proton beam-irradiated HaPPSFs were carbonized at 800 degrees C under an inert atmosphere, resulting in the formation of HaPCFs. The prepared HaPCFs were found to have pseudo-graphitic structures containing both ordered and disordered graphitic structures. The prepared HaPCFs showed a good electrical conductivity.
