摘要/Abstract

摘要： 测定了25℃不同比例的C₁₀F₁₉O(C₂H₄O)₉H与C₈H₁₇C₆H₄O(C₂H₄O)₁₀H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。

Abstract: The surface adsorption and micelle formation of the mixed aqueous solution of fluorocarbon and hydrocarbon chains nonionic surfactants (C₁₀F₁₉O(C₂H₄O)₉H and C₈H_l7C₆H₄O(C₃H₄O)₁₀H) have been investigated. The surface tension of the mixed solution has been determined by the drop-volume method.The results indicate that(1) there is no completely miscible micelle but essentially the individual micelle(C₁₀F₁₉O(C₃H₄O)₉H and(C₈H_l7C₆H₄O(C₃H₄O)₁₀H) in the mixed aqueous solution, (2) surface mole fractions calculated by both methods are essentially consistent with each other, (3) the molecular interaction parameters (βσ) are of positive values. All of these indicate the real existence of "mutual phobicity" between the fluorocarbon and hydrocarbon chains in the mixed system.
