✦ Synopsis

The pore density of the irradiated polymer per unit surface area is identical to the fluence (number of ions per 1 cm 2 ). After carbonization the pore density increased almost twofold due to the shrinkage of the polymer. In the case of the sample in Fig. , irradiated with the fluence of 10 8 cm À2 , the pore density of 1.8 • 10 8 cm À2 was obtained after 45% surface shrinkage during carbonization. The shrinkage of the pore diameter is also observed after carbonization.

We have demonstrated a new approach for the production of porous glassy carbon membrane with the complex 3D topology. The presented results are an illustration of the potential of this fabrication technique. It is also important to note that carbon pores with different shapes can be fabricated by changing the processing conditions during irradiation and chemical etching of the Kapton film. Porous glassy carbon membrane can be designed to meet specific needs of various applications such as catalyst support, electrodes for biosensors, electrochemical double layer capacitors, fuel cells and gas separation.
