✦ Synopsis


The structural changes that cause the change in interlayer spacing of a surfactant-templated zirconium oxide film have been studied using neutron diffractometry. We report that the film after drying on a glass substrate swells slightly through the addition of benzene by up to 4 A ˚on a lattice parameter of about 36 A ˚. The (0 0 1) and (0 0 2) diffraction peak widths, positions and areas of a swollen film were monitored as a function of benzene desorption. Disorder of the lamellar mesophase is considered as a cause of the observed effects on the diffraction signals.

The bars were then anodized in 1% KOH solution at room temperature to produce "stepgages." This was done by dividing each bar into l-cm sections on which successively increasing oxide film thicknesses were produced by anodizing from 0 to 150 V in 10-V increments. Each section was held at voltage one
