摘要
对一种全氟辛基两性磷酸酯氟碳表面活性剂协同作用进行了研究,考察了该表面活性剂与无机盐、阴离子碳氢表面活性剂、阴离子氟碳表面活性剂和非离子氟碳表面活性剂的复配性能,并对结果进行了讨论。研究表明:该两性磷酸酯氟碳表面活性剂自身表面张力为24.0 mN/m;电解质氯化钠对该两性磷酸酯氟碳表面活性剂影响显著,可使表面张力下降到22.4 mN/m;阴离子碳氢表面活性剂十二烷基硫酸钠(SDS)可使表面张力降至21.4 mN/m;阴离子氟碳表面活性剂全氟丁基磺酸钾和四乙基全氟辛基磺酸铵分别使表面张力降至20.9 mN/m和20.2 mN/m;而非离子氟碳表面活性剂N-乙基-N-聚氧乙烯(9)醚-全氟辛基磺酰胺能使表面张力降至20.9 mN/m。
Synergism of a perfluorooctyl phosphoric ester arnphoteric surfaetant was studied. The blending behavior of this surfactant against inorganic salt, anionic hydrocarbon based surfactant, anionic; fluorocarbon based surfactant and nonionic fluorocarbon based surfactant were investigated, with the experiment results discussed. The research results indicated that the surface tension of this phosphoric ester fluorocarbon amphoteric surfactant is 24.0 mN/m. Electrolyte such as NaCl has remarkable influence on this phosphoric ester fluorocarbon amphoteric surfactant and deduces the surface tension to 22.4 mN/m, Blending with anionic hydrocarbon based surfactant, sodium dodecyl sulfate could depress the surface tension to 21.4 mN/m. Blending with anionic fluorocarbon surfactants, such as potassium perfluoro butanesulfonate and tetraethylammonimn perfluorooctanesulphonate, could reduce surface tension to 20.9 mN/m and 20.2 raN/m, and the nonionic fluorocarbon surfactant, such as N - ethyl - N - polyethoxylene （9） - perfluorocctanesulfonylamide, makes it to 20,9 mN/m.
