测定了25℃不同比例的C_(10)F_(19)O(C_2H_4O)_9H与C_8H_(17)C_6H_4O(C_2H_4O)_(10)H混合水溶液的表面张力,研究混合水溶液的表面性质与胶团形成。用两种不同方法计算在表面上的表面成份、分子之间相互作用参数(β_σ)。结果表明,在非离子型碳氟和碳氢表面活性剂混合水溶液中,两种表面活性剂基本上各自形成胶团;表面分子相互作用参数皆为正值;表明此混合体系中碳氟链与碳氢链之间互疏作用的存在。
The surface tension of mixed aqueous solutions of C_ (10) F_ (19) O (C_2H_4O) _9H and C_8H_ (17) C_6H_4O (C_2H_4O) _ (10) H with different proportions was measured at 25 ℃ to study the surface properties and the formation of micelles . Two different methods were used to calculate the surface composition on the surface, the interaction parameter between molecules (β_σ). The results showed that the two surfactants almost completely formed micelles in the mixed aqueous solution of non-ionic fluorocarbon and hydrocarbon surfactant, and the molecular interaction parameters of the surface were all positive. Hydrocarbon chain interaction between the existence of sparse.
