ABSTRACT

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.

摘要

通过两个简单的步骤制备具有特殊润湿性的棉织物。以3-（甲基丙烯酰氧基）丙基三甲氧基硅烷（MSPMA）为试剂，在织物表面接枝硅氧基团，然后用（3-巯基丙基）三乙氧基硅烷（MPTES）在紫外光下与接枝织物反应。硫醇反应原理。同时，在相同的实验条件下，对不同孔径的棉织物进行改性，得到不同孔径的改性棉织物。所得织物具有较好的疏水亲油效果，其水接触角可达146.7°，对不同油水混合物的分离效率优于94%。此外，
