Abstract

The synthesis of silica nanotubes in anodic aluminum oxide membranes (AAO) using the surface sol-gel (SSG) technique was reported. To attempt to understand the dynamics of the tube growth, the process was monitored by transmission electron microscopy (TEM) and SiO2 mass uptake measurement. While still in the membrane, the SiO2-coated pore can be electro-chemically filled with metal and then released by etching in acid to give free-standing insulated wires. Such insulated wires were electrically characterized, and reported that the SSG method gives a very high-quality dielectric oxide.
