Sponge-like superhydrophobic and superoleophilic materials are attracting significant attention for effective cleanup and recovery of spilled oils from water. We report on the synthesis of TiO2 nanoparticle/polyurethane (TPU) composite foam substrate and its surface modification with tetradecylamine (TDA)-amidated graphene oxide (GO-TDA), thereby forming superhydrophobic and superoleophilic TPU-GO-TDA sorbent for oil spill clean-ups. Spectroscopic analyses confirmed that TDA was successfully grafted onto GO and the reduced GO by TDA was successfully grafted onto the TPU foam. Sorption experiments with engine oil, crude oil, silicone oil, and chloroform demonstrated that the TPU-GO-TDA foam was an effective sorbent with sorption capacity of 20.2–62.4 times its own weight. The absorbed oils in the sorbent could be recovered simply by squeezing the oil-laden foam. The much higher selectivity to oils and better reusability of the TPU-GO-TDA foam than commercial sorbents make the TPU-GO-TDA foam promising for the separation and recovery of spilled oils and organic solvents from water.

负载TiO 2纳米粒子的聚氨酯泡沫的合成及其增强溢油净化性能的改性。
海绵状的超疏水和超亲油材料正引起人们的极大关注，它们需要有效地清理和从水中回收溢油。我们报道了TiO 2的合成纳米颗粒/聚氨酯（TPU）复合泡沫基材及其经十四烷基胺（TDA）修饰的氧化石墨烯（GO-TDA）的表面改性，从而形成超疏水和超亲油的TPU-GO-TDA吸附剂，用于溢油清理。光谱分析证实TDA已成功接枝到GO上，而TDA还原的GO已成功接枝到了TPU泡沫上。用机油，原油，硅油和氯仿进行的吸附实验表明，TPU-GO-TDA泡沫是一种有效的吸附剂，其吸附能力是其自重的20.2–62.4倍。吸附剂中吸收的油可以简单地通过挤压含油泡沫来回收。
