Creativity Award Extension: Interfacial Rheology- Instrumentation, Theory and Applications (Supplement)

界面流变学的基础研究，包括实验和理论工作，正在应用于泡沫和乳状液稳定性、表面活性剂驱油提高原油采收率和薄液膜工艺。纵波技术与横向毛细波法相结合，被用来检测表面张力的变化，并确定表面活性剂溶液(膜)在液-气和液-液界面上的动态表面性质。利用改进的表面波技术，结合显微干涉装置，研究了与泡沫和乳状液体系有关的液体表面活性剂薄膜的动态行为。最后，研究了表面粘性和弹性在薄膜稳定中的作用。

Afundamental study in interfacial rheology, involving both experimental and theoretical work, is being conducted with applications to foam and emulsion stability, enhanced oil recovery by surfactant flooding, and thin liquid film processes. The longitudinal wave technique, combined with a transversecapillary wave method, is being developed to detect surface tension changes and to determine the dynamic surface properties of surfactant solutions (films) at both liquid-gas and liquid-liquid interfaces. The improved surface wavetechnique, together with the microinterferometric apparatus, are used tocharacterize the dynamic behavior of thin liquid surfactant films associated with foam and emulsion systems. Finally, the role of surface viscosity and elasticity in the stabilizing of these films is investigated.
