【 摘 要 】

Membranes of nanoporous aluminum oxide (alumina) have been obtained using the electrochemical etching technique under varying technological regimes. The basic geometrical parameters including the thickness of the membrane, the average pore size, and the pore size distribution were determined by measuring the ultraviolet-infrared transmittance spectrum. The process of the charged particles transmission through nanoporous alumina membranes with a pore diameter of about 20 nm was studied.
