AerogelWe are developing a flexible, transparent window film that can be applied onto single-pane windows. Our approach for thermal barrier is based on liquid crystalline phases of nano-cellulose aerogel that have low-emissivity properties, which will help prevent heat loss through windows. We plan to produce the thermal barrier using low-cost cellulose nanorods synthesized from food industry waste. We aim to produce a film that the consumer can easily apply, which could decrease costs by eliminating professional installation labor expenses.
