In this proposal a new approach towards fast and efficient production of organic aerogels is suggested. It is based on the use of carbon dioxide in all steps of the gel formation. The main objective is to investigate the mechanisms resulting in the accelerated solvent exchange and gelation process of organic gels in presence of carbon dioxide at elevated pressure, which results in the aerogels with unusual textural properties and very low thermal conductivity. The understanding of these mechanisms should enable the integration of the fast solvent exchange under pressure and CO2-induced gelation into the production of the bio-based organic gels. This process should allow significant shortening of the overall process time resulting in aerogels with the structural properties comparable or better than the state of the art.

在这项建议中，提出了一种快速有效地生产有机气凝胶的新方法。它的基础是在凝胶形成的所有步骤中使用二氧化碳。主要目的是研究在二氧化碳存在下，有机凝胶在高压下加速溶剂交换和凝胶过程，从而导致气凝胶具有特殊的质构性质和非常低的导热系数的机理。对这些机理的理解应该能够将压力下的快速溶剂交换和二氧化碳诱导的凝胶整合到生物基有机凝胶的生产中。该工艺应能显著缩短整个工艺时间，从而得到结构性能可与当前技术水平相当或更好的气凝胶。
