查询词典 alumina

Porous alumina templates with different apertures were fabricated by changing the oxidation voltage in two-step anodic oxidation, and then Cu nanowires were synthesized in porous alumina by the alternating current electrochemical deposition method. The Cu/PAA was analyzed by SEM and XRD, the results have shown that Cu nanowires were indeed synthesized in porous alumina which had the same diameter and good structure of wire grating.
