A cotton fabric with special wettability was prepared in two simple steps. The surface of the fabric was grafted with silicon-oxygen group using 3-(methacryloyloxy) propyl trimethoxysilane (MSPMA) as the reagent, and then (3-mercaptopropyl)triethoxysilane (MPTES) was used to react with the grafted fabric under ultraviolet light according to the principle of thiolene reaction. Meanwhile, the modified cotton fabrics with various pore sizes were obtained via modifying the cotton fabric with different pore size under the same experimental conditions. The as-prepared fabric had a better hydrophobic and lipophilic effect, whose water contact angle could be up to 146.7° and the separation efficiency for different kinds of oil/water mixtures was better than 94%. In addition, the pore sizes of cotton fabrics had a great effect on the rate of oil/water separation, which increased with the increase of the pore size.
一种具有特殊润湿性的棉织物通过两步简单的方法制备得到。首先，用 3-(甲基丙烯酰氧)丙基三甲氧基硅烷（MSPMA）作为试剂，使织物表面接枝硅氧基团，然后根据硫烯反应的原理，用（3-巯丙基）三乙氧基硅烷（MPTES）在紫外光下与接枝的织物反应。同时，通过在相同的实验条件下用不同孔径的棉织物对其进行改性，得到了具有不同孔径的改性棉织物。所制备的织物具有更好的疏水性和亲油性效果，其水接触角可达 146.7°，对不同种类的油水混合物的分离效率均优于 94%。此外，棉织物的孔径对油水分离速率有很大的影响，随着孔径的增大而增加。
