随着工业含油废水的日益增多和溢油事故的频繁发生，对油水分离的要求越来越高。在这里，通过将壳聚糖（CS）和十六烷基三甲氧基硅烷（HMTS）-g-TiO 2逐层（LBL）沉积在纸张表面并随后进行热处理，成功制备了超疏水/超亲油性纸张。表征了CS/HTMS-g-TiO 2多层膜在改性纸上的形成。并对改性后纸张的润湿性和物理强度进行了测试。经（CS/HTMS-g-TiO 2）20多层膜改性和热处理后的纸张表现出超疏水性（水接触角为167.4°）和超亲油性（油接触角为0°）。该纸具有与原纸相当的抗张强度和优异的自清洁性能。所制备的纸还可以有效地分离不混溶的油-水混合物和仅由重力驱动的油包水乳液。所得纸表现出稳定的可再循环性、高的环境和机械耐久性。因此，这种LBL改性的纸可用于溢油清理和工业含油废水处理。图形摘要
AbstractOil/water separation is highly desired due to increasing industrial oily wastewater and frequent oil spill accidents. Here, superhydrophobic/superoleophilic paper was successfully fabricated by the combination of layer-by-layer (LBL) deposition of chitosan (CS) and hexadecyltrimethoxysilane (HMTS)-g-TiO2on paper surface and subsequent heat treatment. The formation of CS/HTMS-g-TiO2multilayers on modified papers was characterized. The wettability and physical strength of the modified papers were also examined. The paper modified with (CS/HTMS-g-TiO2)20multilayers followed by heat treatment showed superhydrophobicity with a water contact angle of 167.4° and superoleophilicity with an oil contact angle of 0°. This paper had comparable tensile strength to that of original paper and excellent self-cleaning performance. The as-prepared paper could also effectively separate both immiscible oil–water mixtures and water-in-oil emulsions solely driven by gravity. The obtained paper exhibited stable recyclability, high environmental and mechanical durability. Therefore, this LBL-modified paper could be useful for oil spill cleanup and industrial oily wastewater treatment.Graphical abstract
