【 摘 要 】

Membranes of nanoporous aluminum oxide (alumina) have been obtained using the electrochemical etching technique by varying technological regimes. The surface morphology and cleavages of obtained experimental samples are studied using scanning electron microscopy (SEM). The optical transmission measurements were performed on a spectrophotometer in the wavelength range of 190-1000 nm. It is possible to determine the average size and the dispersion of the pore diameter by UV- visible transmittance spectrum measuring.
