摘要
En 中文
Smart control of surface wettability by ionic liquids (ILs) is significant for designing IL-related intelligent materials and devices. Herein, we present mixed molecular brushes comprised of poly(phenylethyl methacrylate) and 1H,1H,2H,2H-perfluorodecyltrimethoxysilane (PPhEtMA-co-PFDMS) grafted surfaces that are capable of dynamically regulating 1-ethyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide ([EMIm][NTf2]) wettability. H-1 NMR and quartz crystal microbalance characterization demonstrate that the wettability changes result from a temperature-dominated cation-p interaction between [EMIm][NTf2] and PPhEtMA-co-PFDMS brushes.
