The results showed that this series of perfluoroalkyl cationic fluoride surfacetant is applicable to strong acid conditions, resistant to salt and with high surfaceactivity. (此后一句我给省了，同前一句基本是同意)。 Addition of salt could improve the surfactant’s performance significantly, reducing the CMC of the surfactant. Taking the chain length influences into consideration, the six F-C numbered PFH-MC is the first choice with a comparable CMC with PFO-MC but a lower dose, and lower produce-cost than PFO-MC due to shorted C-F chain, while PFB-MC is the best choice when environment-protection and bio-degrade is taken into account. |
