Abstract
Highly ordered carbonized nanoporous membranes are produced by ion-beam treatment ofself-assembled block copolymer precursor films. The membranes are electrically conductive,as verified by scanning tunnelling microscopy (STM) measurements. The carbonizationdegree is investigated by means of Raman and infrared (IR) spectroscopy, and themorphology of the films via transmission electron microscopy (TEM). Domains of perfecthexagonal order of the pores are visualized via digital interference of a TEM image of amembrane with computer-generated triangular lattices, producing specific moiréfringes. This novel material could be interesting for applications in nano-catalysis,micro-electronics, and as the grid for STM and TEM imaging of free-standing nano-objects.
