采用一种简单的共沉淀法在聚氨酯海绵基体上负载磁性纳米粒子,在获得磁性的同时也增加了材料的表面粗糙度,后经过甲基三氯硅烷修饰得到超疏水性同时兼具有超亲油性的海绵材料。通过X射线衍射(XRD)、扫描电镜(SEM)、X射线光电子能谱(XPS)、红外光谱(FT-IR)、磁学测量系统(VSM)等测试手段对所制备的材料进行了表征。结果表明:所制备的磁性超疏水海绵对于各种不同的油脂都具有较好的吸附能力,吸油量可以达到自身质量的18.4～25.3倍,同时具有从油水混合物中选择性吸油的能力。因此,所制备的超疏水磁性材料在油水分离领域具有一定的应用价值。
A simple coprecipitation method was used to load magnetic nanoparticles on polyurethane sponge matrix,which not only rendered the material magnetism but also increased its surface roughness.Subsequently,the material was modified with methyl-trichlorosilane to obtain the sponge material with superhydrophobic and superlipophilic properties.The samples were characterized by XRD,SEM,XPS,FT-IR,and VSM.The results showed that the prepared magnetic superhydrophobic sponge exhibited good adsorption capacity for various kinds of oils and fats,the oil absorption capacity could reach 18.4～25.3 times of its own weight,and it had the ability to selectively absorb oil from oil-water mixture.Consequently,the prepared magnetic superhydrophobic material had certain application value in the field of oil-water separation.
