摘要：

Lignin-containing cellulose nanofibers prepared from sugarcane bagasse was used as the substrate to fabricate the superhydrophobic membrane for oil-water separation. The superhydrophobic membrane with a water contact angle of 159.5 degrees was obtained by a facile dipping method based on triclorocadadecylsilane (OTS). The lignin retained in the membrane not only enhanced the hydrophobicity of the membrane, but also contributed to the performance of oil-water separation. When the content of lignin reached 17.53 %, the separation efficiencies of the membrane for diesel and dichloromethane could reach 96 % and 86 %, respectively. Meanwhile, the membrane also showed good oil separation flux up to 716.4 L/(m2 & sdot;h) for dichloromethane, and good recyclability, presenting a promising oil adsorbent in oil spill recovery and environmental protection.
