The present invention relates to hydrophobic organic aerogels obtained by reacting an isocyanate compound and an epoxy compound in the presence of a solvent. The aerogels according to the present invention are hydrophobic high-performance materials (lightweight, with low thermal conductivity, low shrinkage, and high mechanical properties). 本发明涉及通过使异氰酸酯化合物与环氧化合物在溶剂的存在下反应而获得的疏水性有机气凝胶。根据本发明的气凝胶是疏水性高性能材料(轻质，具有低热导率、低收缩率和高机械特性)。
