pH-responsive surface layers consisting of porous polymer monoliths containing thiol groups have been prepared via a "thiol-ene" click reaction using a mixture of hydrophobic and ionizable unsaturated "ene" compounds. A proportion of these two "ene" reagents controlled the wettability of the surface that varied with pH, and enabled reversible switching between superhydrophilic and superhydrophobic properties.
通过“硫醇-烯”点击反应，使用疏水性和可离子化的不饱和“烯”化合物的混合物，制备了由含有硫醇基团的多孔聚合物整体构成的pH响应表面层。这两种“烯”试剂的比例控制了随pH变化的表面润湿性，并实现了超亲水和超疏水性质之间的可逆切换。
