一、测定了全氟醚系列阳离子季胺盐及非离子型氧化物含氟表面活性剂、最低表面张力、临界胶束浓度、表面过剩吸附量、分子在表面上占有截面积、以及在环已烷及汽油上的扩散系数。二、得到下列几个结论: 1.FCI-n_2季胺盐,FCI-n_3季胺盐,FCO-n_2氧化物最低表面张力均为15.1达因/厘米,FCO-n_1氧化物表面张力17.2达因/厘米低于FCI-n_1季胺盐18.5达因/厘米。 2.全氟醚系列氧化物的临界胶束浓度比相应的全氟醚季胺盐低。
First, the determination of the perfluoroether cationic quaternary ammonium salt and non-ionic oxide fluorosurfactant, the lowest surface tension, the critical micelle concentration, the excess surface adsorption, molecules occupy the cross-sectional area on the surface, Diffusion coefficient on alkane and gasoline. The following conclusions are obtained: 1. The lowest surface tension ofFCI-n_2 quaternary ammonium salt, FCI-n_3 quaternary ammonium salt and FCO-n_2 oxide are both 15.1 dyne / cm and the surface tension of FCO-n 1 oxide is17.2 dyne / Cm below the quaternary ammonium salt of FCI-n_1 18.5 dyne / cm. 2. The perfluorinated ether oxide has a lower critical micelle concentration than the corresponding perfluoroether quaternary ammonium salt.
