CMC values determined by surface tension using the Wilhelmy method.

Semifluorinated polymer CMC (log(M)) Particle Size (nm)a
mPEG550-OPFtBMONO N/Ab 4.4 ± 1.2 (99.9 %), 134.6 ± 61.4 (0.1 %)
mPEG1k-OPFtBMONO N/Ab 68.9 ± 35.8 (100 %)
mPEG2k-OPFtBMONO N/Ab 32.7 ± 7.8 (38.1 %), 153.8 ± 82.7 (61.9 %)
mPEG1k-OPFtBTRI −5.0 ± 0.1 11.1 ± 2.8 (99.7 %)
mPEG2k-OPFtBTRI −5.3 ± 0.1 11.8 ± 3.6 (99.8 %)
mPEG1kF13 −6.3 ± 0.1 11.9 ± 1.3 (99.9 %)
mPEG2kDSPE −4.9 ± 0.2 13.9 ± 1.6
a

Particle sizes of semifluorinated polymer measured by DLS as determined by volume. Data is given with the standard deviation. Each measurement was performed above the measured CMC (10 mM) and was repeated three times (n = 3). (%) signifies the percent of total particles of that particular size by volume.

b

N/A signifies that no CMC value could be determined since no constant minimum surface tension could be achieved. mPEG2kDSPE is present as a reference compound.
