Effects of Spacer Length on the Surface Properties of Cationic Gemini Fluorosurfactants

A novel class of cationic gemini fluorosurfactants with different spacer and same hydrophobic chain were synthesized. They were structurally characterized by NMR (1H and 19F), FT-IR, ESI-MS and elemental analysis. The equilibrium surface tensions were studied. The results showed that the gemini fluo...

Zusammenfassung:	A novel class of cationic gemini fluorosurfactants with different spacer and same hydrophobic chain were synthesized. They were structurally characterized by NMR (1H and 19F), FT-IR, ESI-MS and elemental analysis. The equilibrium surface tensions were studied. The results showed that the gemini fluorosurfactants with the shorter spacer displayed higher surface activity, lower surface tension (21.48 mN/m) can be reached. Besides, the synergistic properties of these synthesized gemini fluorosurfactants with sodium dodecyl benzene sulfonate (SDBS) were investigated.
