Cellulose acetate aerogel was prepared based on the cross-linking reactions between hydroxyl groups of cellulose diacetate and isocyanate groups of 2, 4-toluene diisocyanate (TDI) [1].Since the reaction is insufficient, some hydroxyl groups remain in cellulose acetate aerogel, which makes the aerogel hydrophilic and restricts its application in moisture atmosphere.Compared with physical modification using some hydrophobic metal oxides [2], chemical modification using chemical surfactant [3] can be more effective for addressing this issue because of the strong connection between chemical surfactant and aerogel.
