Mechanical and Adiabatic Properties of Silica Aerogel Doped with TiO₂ Nanowire

Abstract:

A novel silica aerogel insulation composite was prepared by using TiO₂ nanowires as modifier via sol-gel processing and supercritical drying methods in order to address issues of the poor mechanical and the infrared shading performance of silica aerogel. The effects of TiO₂ nanowire content on the mechanical and adiabatic performance were investigated by X-Ray diffraction (XRD), nitrogen adsorption (BET), field emission scanning electron microscopy (FESEM), static compression test and thermal analysis. The results show that TiO₂ nanowire reinforced aerogels had great thermal insulation properties, while high surface area, low density and mechanical strength were retained.
