摘要：Fluorine-containing block copolymer ionomers were prepared by atom transfer radical polymerization (ATRP) of 2-[(perfluorononenyl)oxy] ethyl methacrylate (FNEMA) using bromine-endcapped poly (styrene) (PStBr) as macroinitiators, followed by partial sulfonation of the styrene blocks. The formation of the block copolymers before sulfonation was confirmed with gel permeation chromatography (GPC) and H-1-NMR. The sulfonation products were characterized by Fr-IR and elemental analysis. Furthermore, their solution behavior and wettability were examined and comparied with those of the parent copolymers. The results show that the ionomers, especially the metal salt ionomers exhibit higher viscosity than that of the parent block copolymers. Although the polar groups-sulfonated groups were introduced to the copolymer, the film of the ionomer kept high hydrophobic ability.
