Preparation of Carbonized Kapok Fiber/Reduced Graphene Oxide Aerogel for Oil?Water Separation

Carbonized composite aerogel was fabricated based on kapok fibers (KFs) and graphene oxide (GO) through hydrothermal and carbonizing reactions. The as?prepared carbonized kapok fiber/reduced graphene oxide (CKF/RGO) aerogel exhibited special features including lightweight (8.5 mg cm?3), fire?resistance, stable structure, hydrophobicity and oleophilicity. The wettability of KF/GO aerogel was transformed to hydrophobicity after carbonization, which imparted CKF/RGO aerogel with distinct ability for oil?water separation. The CKF/RGO aerogel was able to adsorb oil liquids up to 110 times of its own weight. The sorption capacity of CKF/RGO aerogel was still higher than 90% of initial sorption capacity after 11 sorption?combustion cycles of n?hexane solvent.
