Abstract

Titania foams were prepared by using titanium tetraisopropoxide (TTIP) as the alkoxide. Formide was used as the polar liquid and the triblock copolymer (ethylene glycol)₂₀-(propylene glycol)₇₀-(ethylene glycol)₂₀ served as the surfactant. A solution of 1.75% by weight of the surfactant in FA served as the polar phase. The apolar phase was a mixture of titanium tetraisopropoxide, isooctane and silicon oil in different concentrations. Equal volumes of the two solutions were mixed in N₂ atmosphere and agitated until a viscous emulsion formed. The emulsion was later exposed to the atmosphere. Water was supplied to the emulsion using a filter paper moistened with a few drops of water. Overall, this process enabled to produce titania foams that are highly porous and with a microstructure consisting of very thin spherical shells.
