Porous Silica Films as Thermally Insulating Coatings on Windows

The deposition of transparent, porous silica films as thermally insulating coatings on windows will help reduce energy costs in buildings and homes. 90% porous silica has been characterized for its thermal and optical properties showing surprisingly low conductivities compared to estimates. Film adhesion, stress, and transparency have shown to be major hurdles during the development of these coatings and will be the focus of future work.
