Aerogels are super-lightweight (with density as low as air) materials with extremely low thermal conductivity, and therefore are promising in thermal insulation applications. Currently, most aerogels are derived from silica or synthetic polymers, which are generally brittle and not sustainable. In this project, the University of British Columbia (Sustainable Functional Biomaterials lab) will work with Lululemon to develop new technologies in synthesizing cellulosic aerogel for thermal management in clothing. The objectives of this project include developing mechanically robust aerogel from sustainable cellulosic materials that could sustain machine wash and mechanical abrasion; and optimizing the cellulose-based aerogel for improved thermal insulation properties under compression. ****

气凝胶是一种具有极低导热系数的超轻质(密度与空气一样低)的材料，因此在隔热应用方面很有前途。目前，大多数气凝胶是从二氧化硅或合成聚合物中提取的，这些聚合物通常很脆，不可持续。在这个项目中，不列颠哥伦比亚大学(可持续功能生物材料实验室)将与Lululemon合作开发合成用于服装热管理的纤维素气凝胶的新技术。该项目的目标包括从可持续的纤维素材料中开发出机械坚固的气凝胶，这种材料可以承受机器清洗和机械磨损；并优化基于纤维素的气凝胶，以改善压缩下的隔热性能。****
