摘要:

针对目前用于油/水分离的超疏水材料普遍存在的原料不环保、不可降解、涂层耐久性差等缺点,采用简便的浸渍法,制备了一种环保、工艺简单且性能优良的超疏水材料。首先,使用水性聚氨酯(WPU)将聚甲基丙烯酸甲酯-甲基丙烯酸缩水甘油酯P(MMA-r-GMA)微球固定在棉织物表面,构造微纳米级粗糙结构。其次,通过水解-缩合反应,将无毒的十六烷基三甲氧基硅烷(HDTMS)与甲基三乙氧基硅烷(MTES)锚定在棉织物表面,制备得到超疏水棉织物。结果表明,改性棉织物接触角最高可达157.3(°),滚动角为5(°)。同时具有很好的耐溶剂性,在酸碱溶液中浸泡30 min后,接触角几乎无变化。油水分离效率最高可达97.8%,即使在经过10次循环分离之后,油水分离效率仍然在95%以上。该超疏水织物具有出色的油水分离效率和优良的稳定性,可用于可持续且环保的油水分离领域。

Abstract:

In view of the common drawbacks of superhydrophobic materials used for oil/water separation, such as unenvironmental raw materials, non-degradability and poor coating durability, etc., a simple and convenient impregnation method was adopted to prepare an environmental-friendly, excellent superhydrophobic material. Firstly, polymethyl methacrylate-co-glycidyl methacrylate P(MMA-r-GMA) polymer microsphere was fixed on the surface of cotton fabric using waterborne polyurethane (WPU) to construct micro-nano rough structure. Secondly, through a hydrolysis-condensation reaction, non-toxic hexadecyltrimethoxysilane (HDTMS) and methyltriethoxysilane (MTES) were anchored on the surface of the cotton fabric to prepare a superhydrophobic cotton fabric. The results show that the contact angle of the modified cotton fabric is up to 157.3(o) and the rolling angle is 5(o). At the same time, it has good solvent resistance, and the contact angle hardly changes after being immersed in an acid-base solution for 3 h. The oil-water separation efficiency can reach up to 97.8%, even after 10 cycles of separation, the oil-water separation efficiency is still above 95%. It can be seen that the super-hydrophobic fabric prepared by this research has excellent oil-water separation efficiency and excellent stability, and can be used in the field of sustainable and environmentally-friendly oil-water separation.
