摘要

The interaction between biological surfactant sodium deoxycholate (NaDC) and nonionic surfactants polyoxyethylene (n) nonylphenol ether (NPn) for the formation of micelles in aqueous solution were investigated. Surface tension, interfacial dilational viscoelasticity, and transmission electron microscopy (TEM) were characterized to systematically study the interaction between NaDC and NPn in buffer solution. At last, the mechanism of the interaction between NPn and NaDC were analyzed. The surface tension results show that the interaction between NaDC and NPn was displayed synergism action. The composition of the mixed systems has been estimated on account of the regular solution theory, Clint’s equation, Rubingh theory and Rosen theory. The surface dilational rheology provided abundant effective information on the feature of adsorbed layers. From the oscillating barrier measurements, the peak values of the dilational modulus moved to lower concentrations in NaDC/NPn binary system compared to single surfactant. The dilational elasticity of the binary system decreased distinctly on the basis of the rigid structure of NaDC. The interaction of these two substances was proved directly by TEM images, that the boundaries of the aggregates are clearer due to the protection of NPn molecules. The new complex systems have potential application in environmental protection.

研究了生物表面活性剂脱氧胆酸钠（NaDC）与非离子表面活性剂聚氧乙烯（n）壬基酚醚（NPn）在水溶液中形成胶束的相互作用。通过表征表面张力，界面膨胀粘弹性和透射电镜（TEM）来系统研究缓冲液中NaDC与NPn的相互作用。最后，分析了NPn与NaDC的相互作用机理。表面张力结果表明，NaDC与NPn之间的相互作用表现出协同作用。混合系统的组成是根据正解理论，克林特方程，鲁宾赫理论和罗森理论进行估算的。表面膨胀流变学提供了有关吸附层特征的大量有效信息。通过振荡势垒测量，与单一表面活性剂相比，在NaDC / NPn二元体系中，膨胀模量的峰值移至更低的浓度。在NaDC的刚性结构的基础上，二元体系的膨胀弹性明显降低。 TEM图像直接证明了这两种物质的相互作用，由于NPn分子的保护，聚集体的边界更加清晰。新的复杂系统在环境保护方面具有潜在的应用。
