摘要：A series of amphiphilic copolymers with fluorocarbon groups (Poly(AMPS-co-FS), PAMFS) were synthesized by the radical copolymerization of sodium 2-acryamido-2-methylpropanesulfonate (AMPS) and styrene derivatives with a fluorocarbon side chain (FS). The structures and molecular characteristics of PAMFS were confirmed by ~1H-NMR, ~(19)F-NMR, elemental analysis, and static light scattering. The aggregation behavior of the copolymer in aqueous solution was studied by surface tension, electrical conductivity, dynamic laser light scattering, transmission electron microscopy, and fluorescence measurements at different conditions. The results indicated that the surface activity of PAMFS is dependent on the content of fluorocarbon groups in the copolymer structure. The surface tension (γ_(cmc)) and critical micelle concentration of PAMFS decrease with the increase of sodium chloride concentration. The copolymers formed micelle-like aggregates and the fluorocarbon groups exhibited a strong tendency for intermolecular association.
