采用溶胶-凝胶法制备了氟化二氧化硅纳米颗粒（F-SiO2 NPs），并将其固定在丝瓜海绵表面，制备了一种新型的三维超疏水材料。对改性丝瓜海绵的形貌、化学成分和表面润湿性进行了表征，并与未改性丝瓜海绵进行了比较。改性丝瓜海绵表面的水接触角（WCA）高达156度。这种3D超疏水丝瓜海绵可以立即从油/水混合物中去除油。这表明，这种低成本、可再生的丝瓜丝瓜海绵可以有效地作为一种新型的三维超疏水材料用于油水分离。(C) 2018 Elsevier B.V.版权所有
Fluorinated silica nanoparticles (F-SiO2 NPs) were prepared by sol-gel method, and anchored on the surface of loofah sponge, so fabricating a novel three-dimensional (3D) superhydrophobic material. The morphology, chemical composition and wettability of the surface of the as-modified loofah sponge were characterized and compared with those of unmodified loofah sponge. The water contact angle (WCA) on the surface of modified loofah sponge is as high as 156 degrees. Such a 3D superhydrophobic loofah sponge can immediately remove oil from the oil/water mixture. It implies that the low-cost and renewable loofah sponge can be effectively utilized as a novel 3D superhydrophobic material for oil/water separation. (C) 2018 Elsevier B.V. All rights reserved.
