这项工作首次展示了全氟磺酸聚合物 C-F 基团上的化学反应。 Nafion 链显示出原子转移自由基加成到多壁碳纳米管上的化学反应性，并且能够充当原子转移自由基聚合的大分子引发剂。 19F NMR 研究表明，C-F 基团和主链 -CF2 基团是负责反应的活性位点。这些结果无疑可以扩展全氟磺酸聚合物的化学和应用范围以及氟化化合物的原子转移自由基加成/聚合的窗口。
This work reports the first demonstration of the chemical reactions on the C-F groups of perfluorosulfonic acid polymers. The Nafion chains show chemical reactivity for atom transfer radical addition onto multiwalled carbon nanotubes and ability to serve as a macroinitiator for atom transfer radical polymerization. The C-F groups and mainchain -CF2 groups have been demonstrated, under a study with 19F NMR, as the active sites responsible for the reactions. The results could certainly extend both the scopes of chemistry and application of perfluorosulfonic acid polymers as well as the windows of atom transfer radical addition/polymerization to fluorinated compounds.
