Surface-initiated atom transfer radical polymerization (ATRP) of (2,2-dimethyl-1,3-dioxolan-4-yl)methyl methacrylate (1) was carried out from an immobilized initiator on a silicon wafer to result in a high-density polymer brush, which was converted to the hydrophilic polymer brush consisting of 2,3-dihyroxypropyl methacrylate (2) units, successively. The poly(2) brush showed low dynamic friction coefficient in water.
表面引发的原子转移自由基聚合(ATRP)对(2,2-二甲基-1,3-二氧杂环烷-4-基)甲基丙烯酸酯(1)在硅晶片上固定的引发剂进行,得到高密度聚合物刷,随后被转化为由2,3-二羟基丙基甲基丙烯酸酯(2)单元组成的亲水性聚合物刷。聚(2)刷在水中表现出低动态摩擦系数。
