Abstract

Mesomorphic ceramics are inorganic solids with anisotropic superstructures that are derived from lyotropic suspensions. Here we report on the synthesis of amorphous silica nanotubes and their subsequent processing into mesomorphic ceramic thin films. Nanotube synthesis involves the formation of nickel hydrazine complexes within inverse micelles followed silica coating and etching of the core. A lyotropic suspension of silica nanotubes is formed and subsequent blade-coating results in birefringent thin films. Sintering of particle assemblies may result in waveplates with high laser damage resistance.
