研究了加入聚合物对Triton X-114/正辛烷/正丁醇/水组分体系相态的影响.利用次甲基蓝(MB)作为吸附探针,而以(口恶)唑烷氮氧自由基(5-doxyl stearic acid,5-DNS)作为自旋探针,研究了加入聚合物对TX-114/正辛烷/正丁醇/水反相微乳液的微结构影响.结果表明:聚合物添加使W/O微乳液区缩小,而液晶区则更靠近水一端(增溶更多水),该反相微乳液中存在三种状态水:结合水、束缚水、体相水.加入聚合物可以替代先前存在于TX-114聚氧乙烯链上的一些水分子,使其微极性减小,而且使表面活性剂分子在界面上的排列更为松散,本研究结果对探讨聚合物对W/O微乳液微结构的影响及此类体系在其它方面应用有重要意义.
The effect of adding polymer on the phase state of Triton X-114 / n-octane / n-butanol / water component system was studied. Methylene blue (MB) 5-DNS (5-DNS) was used as a spin probe to study the microstructure of TX-114 / n-octane / n-butanol / water reverse microemulsion with addition of polymer. : Polymer addition narrows the W / O microemulsion region while the liquid crystal region is closer to the water end (more water is solubilized). There are three states of water in the reversed microemulsion: bound water, irreducible water, bulk phase water The addition of polymer can replace some of the water molecules previously present in the TX-114 polyoxyethylene chain, resulting in a decrease in micropolarity and a more relaxed arrangement of the surfactant molecules at the interface. The results of this study The effect of polymer on the microstructure of W / O microemulsion and the application of such system in other aspects are of great significance.
