A Nature Energy research briefing published March 16, 2023 described transparent cellulose aerogel films developed for window insulation. Researcher Ivan Smalyukh outlined the team’s work on silanized cellulose aerogel, or SiCellA.
The researchers applied the material to single-pane glass and placed it inside double-pane units. Their tests examined heat transfer and optical properties, with the aim of improving thermal resistance while preserving useful transparency.
The briefing also described films adhered to plastic supports and rolled, a potentially important processing route for retrofit materials. This was more than a proposed simulation: the report discussed fabricated materials and window prototypes.
Manufacturing cost and haze in thicker samples remained development issues. The result did not establish a broadly available installer product, a universal energy-saving percentage or long-term performance in every climate.
