High Surface Activity

The surfactivity of nonionic fluorocarbon surfactants, polyethylene glycol perfluoro-nonyl monoether (C9F17-PEG-n) and diether (C9F17-PEG-n-C9F17), was systematically investigated, including the surface tensions (γ), critical micelle concentration (CMC), cloud point, foaming property and emulsifiability. The relation between their surface performance and their chemical structure of C9F17-PEG-n and C9F17-PEG-n-C9F17were studied. The result showed that this series of fluorocarbon surfactant possessed high surface activity, the CMC < 2.8 × 10-4mol/L and the γCMC< 25 mN/m. Compared to C9F17–PEG-n, C9F17-PEG-n-C9F17have smaller minimum molecular area (Amin), greater saturated adsorption quantity (Γm), lower cloud point, poorer emulsifiability in toluene and greater foaming volume for their aqueous solutions. For either C9F17-PEG-n or C9F17-PEG-n-C9F17, with the increase of the PEG molecular weight (PEG-n), Γmdeclines, Aminincreases and the emulsifiability in toluene becomes better, the CMC, γCMCand cloud point of their aqueous solutions increases, and their foaming volumes increase first and then decline, getting the maximum value at n=1000.
